Custom Shadcn Filters for React and Tailwind CSS. A stepped filter builder with nested attributes, popover value editors and a boolean query tree.
Filters turns a schema of attributes into a filter bar. A user picks an attribute, picks a condition, gives it a value, and the result is one boolean query object you compile into a predicate, a query string or a request body.
The state it edits is a TREE, not a list of chips. FilterQuery is a group of rules combined by and or or, and a group may hold another group, so (A and B) or C is expressible from day one. The chip row renders the flat case of that tree and the advanced builder renders the whole of it, read and written through the same actions, which is why variant picks a chrome rather than a second state model.
The install target moved. The old primitive was a single components/reui/filters.tsx. The rewrite ships fourteen files under , so an existing consumer must delete the old single file after installing, or end up with two different exports one directory apart.
Browse 12 production-ready Shadcn Filters components for dashboards, forms, and product UI. These examples use Base UI primitives from @base-ui/react and stay fully compatible with Shadcn Create so radius, color, and typography match your configured theme.
Browse all 12 Shadcn Filters components for copy-ready layouts, dashboards, and forms built with Tailwind CSS in the ReUI library.
components/reui/filters/FiltersThe registry item pulls six shadcn parts - button, button-group, dropdown-menu, input, popover and tooltip - plus one ReUI item, cascader. @reui/cascader is the heavy one and brings @base-ui/react and @tanstack/react-virtual with it, since every list in this primitive is the cascader, configured: the attribute picker drills through nested fields, the operator menu and each option editor are the same control run flat, and the keyboard, aria-activedescendant, typeahead, RTL keys, windowing and the live region all come from there rather than from a listbox this primitive re-implements. Two npm packages come in directly: class-variance-authority, for the bar's size variants, and date-fns, used only by filters-date.tsx. Nothing in the core imports the date helpers, so that file and its dependency can both be deleted if you do not want a date editor.
Nine of the fourteen files import no UI library at all. filters-types, filters-query, filters-lib, filters-operators, filters-draft, filters-i18n, filters-context, filters-date and filters-dnd pull nothing from Base UI, from radix-ui or from the shadcn parts. Eight of those nine touch no DOM either, which is what lets the query, the operator catalog and the step machine be tested in a node environment with no browser at all. filters-dnd is the exception: it is a pointer engine, so it is library free but not DOM free.
import { Filters } from "@/components/reui/filters/filters"
import { createFilterQuery } from "@/components/reui/filters/filters-query"
import type {
FilterField,
FilterQuery,
} from "@/components/reui/filters/filters-types"const fields: FilterField[] = [
{ id: "title", label: "Title", type: "text" },
{
id: "status",
label: "Status",
type: "select",
options: [
{ value: "active", label: "Active" },
{ value: "archived", label: "Archived" },
],
},
]
export function Toolbar() {
const [query, setQuery] = useState<FilterQuery>(() => createFilterQuery())
return <Filters fields={fields} query={query} onQueryChange={setQuery} />
}fields is the only required prop. Leave query off and the bar keeps its own state, seeded from defaultQuery.
Choosing an attribute commits the rule straight away, so the chip appears reading "Select condition", and picking a condition advances the same popover to the value editor. Escape keeps an unfinished rule rather than dropping it, drawn with a dashed outline, and flattenFilterConditions skips it so a half-built rule can never silently filter nothing.
A query is always a group, never a bare array. The root holds rules and other groups in order, and its combinator says how they join.
const query: FilterQuery = {
id: "root",
type: "group",
combinator: "and",
rules: [
{
id: "r1",
type: "rule",
path: ["status"],
operator: "is",
value: "active",
},
],
}variant picks the chrome. Both read and write the same query, so a saved view built in one opens in the other with nothing converted on the way.
// A flat pill row, for a toolbar over a table.
<Filters fields={fields} />
// The condition builder, hung off a trigger that carries the rule count.
<Filters fields={fields} variant="advanced" />
// The same builder rendered in place, for a sidebar or a settings page.
<Filters fields={fields} variant="advanced" advancedMode="inline" />A field carrying fields renders as a branch the picker drills into. A rule stores the whole path, root first.
const fields: FilterField[] = [
{
id: "name",
label: "Name",
fields: [
{ id: "full", label: "Full name", type: "text" },
{ id: "first", label: "First name", type: "text" },
],
},
]
// A rule on "First name" stores path: ["name", "first"]An option marked exclusive is the row that means NONE OF THE ABOVE. Picking it clears every other pick, and picking anything else clears it.
options: [
{ value: "ada", label: "Ada" },
{ value: "unassigned", label: "Unassigned", exclusive: true },
]The primitive stops at the tree and compiles nothing. There is no SQL here, and that is deliberate: the tree is the integration surface, and SQL is one target beside Prisma, Drizzle, a REST query string and Elasticsearch, none of which a browser serves well.
The query is plain JSON, so it goes on the wire as it stands - no class instances, no functions, and no Date objects, since a date rule stores a relative token. flattenFilterConditions gives you { path, field, operator, values, negated } per rule when a flat conjunction is all you need; walk the tree yourself when the parentheses carry meaning.
Operator arity, custom value editors, date tokens, validation helpers and the full export list are in the API Reference below.
If you already have Filters installed, paste the prompt below into your coding agent. It covers both cases: a session with the ReUI MCP connected, and a plain project where the primitive is reinstalled from the registry.
Migrate ReUI Filters from the flat filter array to the query tree.
STEP 1 - Replace the Filters primitive from the registry.
Case A, the ReUI MCP is available in this session:
- Call search("filters"), then get_component("filters") to read the current API.
- Call get_examples("filters") to see real composition.
- Run the command returned by get_install_command("filters") and overwrite when prompted.
Case B, no ReUI MCP:
- Run: npx shadcn@latest add @reui/filters
- Answer yes when asked to overwrite the existing files.
Every filters file must come from the registry. Do not hand-patch them, do not merge
them by hand, and do not keep a local fork of any of them.
STEP 2 - Delete the old single file.
- The install target moved from components/reui/filters.tsx to the components/reui/filters/
directory. The installer does not remove the file it replaces.
- Delete components/reui/filters.tsx once the install has finished.
- Do not continue until it is gone. If both survive, the project has two different
Filters exports one directory apart, and which one an import resolves to depends on
module resolution order, so the app can typecheck and build and still render the old
primitive against the new props.
STEP 3 - Convert the state from a flat array to a query tree.
- The old state was Filter[], each { id, field, operator, values }, joined by an
implicit AND that was never written down anywhere.
- The new state is a single FilterQuery, which is ALWAYS a group:
{ id, type: "group", combinator: "and" | "or", rules: FilterNode[] }
A FilterNode is either a rule or another group, so nesting is the same shape again.
- Each old filter becomes a rule:
{ id, type: "rule", path: string[], operator: string, value, negated?: boolean }
- Two of those are shape changes, not renames, and both need conversion code:
1. field: string becomes path: string[], root first. A flat field is a one-element
path, so field: "status" becomes path: ["status"]. Nested attributes are the
reason it is an array.
2. values: T[] becomes a single value. A multiselect keeps its array AS that one
value; a single-value operator takes the scalar itself, not a one-element array.
- Wrap the converted rules in a root group with combinator "and". That reproduces the
old implicit-AND behaviour exactly, so existing saved views keep their meaning.
- Anything that persisted filters (localStorage, a saved-view table, a URL param) holds
the OLD shape. Convert on read, and decide explicitly whether to write the new shape
back or to keep converting, because a half-migrated store is the failure mode here.
STEP 4 - Update the component props.
- filters and onChange become query (or defaultQuery for uncontrolled) and onQueryChange.
onQueryChange receives (query, details), where details carries the reason it fired:
add, update, remove, duplicate, negate, reorder, combinator or clear.
- fields changed shape. FilterFieldsConfig, which accepted either a field array or a
group array, becomes a plain FilterField[]. Per field, key becomes id, and id and
label are both REQUIRED now rather than optional.
- A field's type survives the name but not the values. The old union was
"select" | "multiselect" | "text" | "custom" | "separator". The new FilterValueType is
"text" | "number" | "range" | "select" | "multiselect" | "boolean". There is no
"custom" - register an editor and name it with the field's editor prop - and no
"separator", which was a rendering hint rather than a value type.
- Field groups are gone as a separate concept. A field carrying its own fields IS a
branch that the picker drills into, and the rule stores the whole path.
- variant survives the name but changed meaning entirely: "solid" | "default" became
"basic" | "advanced". "basic" is the chip row, "advanced" is the nested condition
builder. If variant="solid" was passed for appearance, delete it rather than mapping it.
- i18n becomes labels, with the operator wording split out into operatorLabels.
- Removed with no replacement: radius, showSearchInput, allowMultiple, menuPopupClassName,
collapseAddButton, enableShortcut, shortcutKey and shortcutLabel.
- Unchanged: size, trigger and className.
STEP 5 - Prove the migration is complete.
Search the whole project. Every one of these must return zero results:
components/reui/filters.tsx
variant="solid"
showSearchInput
allowMultiple
collapseAddButton
enableShortcut
shortcutKey
Then check every <Filters> element: none may still pass filters= or onChange=.
Any hit is a call site that was missed.
STEP 6 - Verify it actually runs.
Typecheck must pass with no errors. Then open each filter bar and confirm: adding a
condition, editing its value in place, removing it, and that a previously saved or
seeded query still loads with the same meaning it had before. If variant="advanced" is
used anywhere, also confirm nested groups render, that switching a group between AND and
OR works, and - if you passed `reorderable` - that drag reordering works.The other six ship exactly as these do and stay browsable on the Filters components page: status and priority color badges, avatar options paged over the wire, a date and a date range editor, sliders as the value editor, typed values in shadcn inputs, and a controlled bar across three sizes and three locales.
The root. Provides every context and renders the chrome variant selects, unless you pass children.
V is the stored value type and O the option payload; both flow into every callback.
disabled and readOnly are not two words for one state, and both are enforced at the action boundary. Every one of the fourteen query writes, plus openCreate, openAmend and dispatchDraft, returns without writing while either flag is set, so no route reaches the query: not the triggers, not a chip's kebab, not Delete or Backspace, not Alt+arrow, not a drag, and not a chrome you compose yourself through children. addGroup is the one mutator that reports the refusal, by returning an empty string, because its callers move focus onto the id it hands back.
What the two flags differ in is what a person can still DO with the bar:
disabled turns it off. Every control takes the native disabled attribute and leaves the tab order.readOnly keeps it readable. Every mutating control stays focusable and carries aria-disabled="true" plus data-readonly, so Tab still reaches the bar, the arrows still rove across the chips and across the builder's cells, and every chip and row keeps its accessible name. The chip row says so through the toolbar's aria-description and the advanced panel through a visible line, both from labels.readOnly; aria-readonly is deliberately not used, because it is not an allowed attribute on role="toolbar", role="group" or role="button". The advanced builder's own trigger stays live under readOnly on purpose: opening the panel is reading, and it is the only place a nested query is legible in full.Controls that would open an editor refuse to open it rather than opening a surface whose every action is a no-op. Because that closes the one route to a value the display had summarized, a locked value control is NAMED with the whole list instead: a chip that shows "2 selected" announces "2 selected: Active, Archived", from labels.valueDetail, and carries the same string as its title in both modes. Editable, the name stays the short form, since pressing the segment is the answer.
Your own trigger is covered too. The trigger you pass to the chip row or to the advanced builder receives the same state the default button gets, so it dims and announces itself without your having to read actions at all. isFilterLocked(actions) and filterReadOnlyProps(actions) are exported for the rest of a chrome you compose yourself.
One thing the flags do NOT do is make the shipped chrome the enforcement point. The refusal lives at the action boundary, so it holds from the render that sets the flag: a consumer effect that calls removeNode in the same commit that turns readOnly on is refused, not run one frame late.
onBeforeQueryChange is the same boundary, opened up. Every write in this component goes through one emitter, so a hook there covers the chip row's Delete, the builder's Alt+arrow, a pointer drop, a menu item and a chrome you composed yourself through children - one hook rather than fourteen props. Return false to refuse the change; return anything else, including nothing, and it commits. details.reason names the action that asked, so per-action policy is a switch in one place:
<Filters
fields={fields}
onBeforeQueryChange={(next, details) => {
if (details.reason === "clear") return confirm("Clear every filter?")
if (countFilterRules(next) > 10) return false
}}
/>It sits BEHIND the lock, and the ordering is deliberate: a disabled or readOnly bar never asks, so the hook can refuse a change but can never approve one the flags have already refused. A refusal is silent by design - nothing is announced and the roving tab stop does not move, because an add the boundary turned down mints no id for focus to land on.
onConvertToAdvanced is the route from a chip row to the builder. The prop IS the switch: variant belongs to you, so a boolean without a handler would draw a menu row that does nothing. Supply one and every chip's kebab grows an Advanced editor item (labels.convertToAdvanced), which is suppressed automatically once variant is already "advanced" - the one place the row would be an offer to go where the user already is.
A query is always a group, never a bare array. FilterQuery<V> IS a FilterGroupNode<V>, and a FilterNode<V> is either a rule or a group.
onQueryChange receives the new query and this object, so you never diff two trees to find out what happened.
Every writer is pure and returns a new tree with structural sharing, so a branch that did not change comes back BY IDENTITY. That is what makes React.memo on a chip hold: editing one filter in a bar of forty re-renders one chip. All of them live in filters-query, and the ones a consumer reaches for most are re-exported from filters as well.
A field is a leaf or a branch, and there is no separate group type: a field carrying fields renders as a branch the picker drills into.
The schema is indexed by signature, not by identity. Fields are almost always an inline array literal, so a memo keyed on the array's identity would miss on every parent render. The primitive computes a cheap content signature each render (ids, labels, types, default operators, option values and labels, operator names, keywords, counts and the presence of each callback) and rebuilds the index only when that changes. Render props are deliberately excluded, because inline JSX recreates them every render, so changing ONLY a render prop with no structural change anywhere will keep serving the previous field objects. Change something structural alongside it, or give fields a stable identity, when a render prop has to update on its own.
Each value type has a catalog. A field's own operators wins outright; otherwise the catalog for its type applies. There is no implicit promotion from select to multiselect based on how many values happen to be picked: the same field offers the same operators at every moment.
In the built-in catalog empty and not_empty carry arity: "none", between and not_between carry "range", and the is_any_of / is_none_of / has_* family carry "many". Everything else is "one". starts_with, ends_with and has_all_of are the built-ins with no inverse, so negating one of them sets rule.negated rather than swapping the operator. Two of the three sit on "text", which is the default field type, so a consumer reading a query with flattenFilterConditions has to honour negated rather than treat it as a rare case.
Which editor renders is decided highest first: the field's own editor, as a component or as a name in the editors registry; then the operator's ARITY, where "range" takes the range editor and "many" takes the multi-select editor WHEN the field is option backed; then the field's type, falling back to text. An arity: "none" operator takes no editor at all, and a "many" operator on a field with no options keeps the editor its type chose and receives an ARRAY.
Arity outranks type because "between" on a number field wants two boxes whatever the field said, and "is any of" on a select wants several picks even though the field is single valued.
By default a built-in select or multi-select leaves its rows exactly where the schema declared them, ticked or not. The check marks already say what is chosen, and most option lists are short semantic sequences (To do, In progress, In review, Done) that a reader learns the shape of, so reordering one under the reader costs more than it buys. A field that wants the picks stacked at the top asks for it with pinSelected: true, and gets the partition described here. Reach for it where the fold is a real problem: 120 countries, a directory paged over the wire, a tag cloud.
Under pinSelected the rows are partitioned into SELECTED then unselected with a full-bleed rule between the two groups, so a long list never hides what is already chosen. Inside each group the order is the schema's, which is a partition and not a sort, so sortSelected: "label" stays opt-in for a people or country list whose order carries no meaning. The pinned group re-partitions LIVE, carrying the highlight across the reorder BY VALUE so nothing scrolls, and sortSelected: "snapshot" freezes the partition at open for a list where a steady pointer target matters more. The partition is memoized on the selection rather than on the query, so typing in a 4,000 row async field filters over the wire without re-partitioning on every keystroke, and the rule between the groups is hidden while a query is narrowing the list, since "your picks, then the rest" is a claim about the whole list. sortSelected works without pinSelected too: with one group it orders that group, which is the whole list.
What every value editor receives.
Returned by useFilterOptions, and handed to every editor as options.
Handed to renderValue, to valueText and to the default display.
The chip row, rendered by default in basic mode.
The Add filter popover and the attribute picker inside it. Collapses to an icon-only button once the query holds a filter, keeping its accessible name.
One popup, ONE panel: the field step. Picking a field commits the rule immediately and the operator menu opens on the chip that was just created, so the popover never holds a second or third step the user has to walk. The draft reducer still models operator and value steps with a Back between them, because they are the headless surface a consumer-composed wizard drives.
The builder itself, with no popup of its own.
Anatomy. The body and a footer. There is NO header strip: it lost its title (a popover opened from a button reading "Advanced filter" does not need to be told what it is), then its subtitle ("In this view, show records" described the first row's own "Where" a second time), and what was left was a rule count the rows already show, a validation summary, and a kebab whose two actions both have another route - the root combinator is the second row's own And/Or toggle, and Clear all is a footer button. The panel keeps the programmatic name - role="group" plus aria-label={labels.advancedFilter} - so a reader who arrows into the popup from somewhere else still meets it.
A condition is a row of TWO BANDS. The content band - [attribute] [condition] [value] - is packed against the leading edge after the combinator column and sized to itself; the action band - [grip] [menu] - is pinned to the trailing edge, with four pixels of room after the kebab. Whatever is left over sits between them. ONE action per row, not three: the trash it used to sit beside duplicated the menu's own destructive Remove, and the grip survives because it is what ARMS the drag, which the row itself cannot do without turning every text selection into a gesture. The pair is drawn as one piece of chrome at muted weight, lifting to bg-background with a hairline under a pointer and while its menu is open.
The footer carries Add filter and Add group as OUTLINE buttons - they are what the footer is for, and as ghosts they read as a caption under a builder full of outlined cells - then, on the trailing edge, the validation summary when there is one and Clear all once the query holds anything. All of them refuse to shrink, so a narrow panel wraps them rather than clipping a label.
The three content cells ask for their own width rather than for a share of the row, and the default is three custom properties declared on the panel:
Each is written as a FALLBACK inside the cell's own flex-basis, not as a declaration on the panel, so the nearest ancestor that names the property wins and there is nothing in between to beat. All of these work:
// Inline: className reaches the panel itself.
<Filters variant="advanced" advancedMode="inline" className="[--filter-field-width:14rem]" fields={fields} />
// Popover: className reaches the popup that CONTAINS the panel, and the value inherits down.
<Filters variant="advanced" className="[--filter-value-width:16rem]" fields={fields} />
// Or on the box you wrapped it in, or in a stylesheet. The cells read the value as inherited, so any ancestor works.
<Card className="[--filter-operator-width:7rem]">
<Filters variant="advanced" advancedMode="inline" fields={fields} />
</Card>Each is a flex-basis and never a min-width, and the difference is the whole reason the trailing controls line up. A binding floor makes a row wider than its box, and a nested row is indented, so it overflows by MORE and the column of kebabs goes ragged; a basis is a preference the cell gives up entirely before the row overflows. Below the default the cells shrink in proportion to it and their labels truncate; above it they do not stretch, which is what leaves the empty space between the content band and the actions.
The panel draws no border, no background and no radius of its own, and there is no prop that hands it one. In popover mode the popover is the surface. Inline, the surface is yours and you make it the ordinary way: wrap the builder in whatever the page already uses.
<Card className="w-full">
<Filters variant="advanced" advancedMode="inline" fields={fields} />
</Card>This used to be an advancedSurface prop that the panel rendered itself AS, so the consumer's element became the panel. It worked, and a wrapper gets the same result with nothing to explain: no rule about which way className merges, no list of the props the panel has to keep stamping onto an element it does not own, and no requirement that your component forward the props it is handed. Two boxes is the honest shape - yours owns the surface and the spacing, the primitive owns everything inside it.
Inline, the panel pads itself by nothing, so your wrapper's padding is the only padding and the builder reads as one box rather than as an inset inside a card. That is the --filter-panel-pad variable: 0.75rem in popover mode, where the popup's content is p-0 and the panel's own padding is what keeps the rows off the popover's edge, and 0px inline. Every strip - the body, the footer, the read-only note - reads that one number, which is what keeps the column of kebabs and the Clear all button on one axis. Override it on either mode if your wrapper wants the padding to come from the primitive instead:
<Filters
variant="advanced"
advancedMode="inline"
className="[--filter-panel-pad:1rem]"
fields={fields}
/>The container queries the rows measure themselves against are declared on the panel's BODY and on every group's list of children, both inside the panel, so a wrapper with its own padding changes how much room a row has and never which element answers the question.
With no conditions at all the panel draws its own empty state - a muted glyph, labels.builderEmpty and, unless the bar is read-only, labels.builderEmptyHint - above the footer rather than leaving the two footer buttons floating in a blank popup. A builder is empty most often because somebody just pressed Clear all, and that press deserves a confirmation.
Every control in the builder derives its size from ONE ladder keyed off the root's size, so the row cells, the icon buttons and the footer agree at every rung. Nothing in the primitive names a height: each shadcn size name resolves to its own per-style padding and its own icon size, so a hardcoded h-8 would be the one control in the app ignoring the style the user picked.
Text controls are the combinator pill, the attribute, condition and value cells, the panel's footer buttons and a value editor's Discard and Apply. Icon controls are every grip and every kebab. filterControlSizes(actions) is exported for a chrome you assemble yourself, so your own cell lands on the same rung.
The chip row's own GAP reads the resolved rung too, not the raw prop, which is what stops the bar's rhythm and the controls in it from answering separately: a size TypeScript would have refused - "lg" from a codebase that has not upgraded - resolves to the default rung once, and the spacing and the heights both follow it.
THE CHIPS RIDE THE SAME LADDER, which they did not before. The argument for exempting them was that ButtonGroup has no size variant, so there was nothing to thread; the flaw in it was that a chip is the largest thing in the bar, so a size that moved everything except the chips looked like a size that did nothing. The thread turned out not to need a variant: the group is items-stretch and no style gives a group's text segment a height, so the pill takes the height of its one definite-height child - the kebab - and sizing the kebab off the icon rung sizes the whole chip. The segments stay one element each, which is what ButtonGroup's direct-child fusion selectors require.
FiltersProps.size deliberately does NOT offer xs, even though the shadcn button ladder has xs and icon-xs. The builder's row is a form, not a toolbar: xs resolves to a 20 to 24px control depending on the style, which is under the 24px minimum WCAG 2.2 Target Size (Minimum) asks of a pointer target that is not inline in a sentence, and this row has two icon buttons sitting side by side at its right edge. sm is already the dense rung, and it now reaches the chip row too, which is where a genuinely dense bar is wanted. xs stays out for a second reason as well: a chip's height comes from its kebab, and icon-xs is a 20 to 24px square in most styles, so an xs bar would be a row of pills whose segments no longer clear their own labels. Adding it is one line in FILTER_CONTROL_SIZES if your own style ladder makes xs big enough.
Only ONE combinator cell per group is interactive, and that is what makes the model SQL-standard rather than per-row mixing. A group has exactly one combinator, so the first row's cell is the static word "Where", the SECOND row's cell is the control that flips the whole group, and every later row echoes the result. Three editable "and"s down a column would imply three independent choices, and a query that mixed them would need precedence rules this model deliberately does not have.
The control is a compact outlined button carrying the word and NOTHING ELSE. It has no disclosure caret, because a combinator is a two-value toggle and a caret would promise a list that does not exist; it no longer has the swap glyph that stood in for one either, because the glyph and the word were centred TOGETHER, which left the word about ten pixels to the left of the two static words in the same column. The outline is what says this one is pressable: it is the only box in the column, and the two static slots are plain muted text with none, because a word that looks pressable and is not is worse than no affordance. Its accessible name is labels.combinatorLabel(word), which puts the word FIRST - the track is fixed and no fixed track fits every language, so a locale whose word overflows draws "a..." and a name of "Change combinator" alone would leave a pointer user unable to find out which of the two it says. Pressing it announces the group's new description through the live region, since the toggle rewrites a whole group and its own label is the only thing on screen that changes.
Mixing is what a nested GROUP is for. A group renders as a bordered card with its combinator pill OUTSIDE it on the leading edge, an eight-pixel drop strip at the top, its children, and a footer holding Add filter on the leading edge and the group's own grip and kebab on the trailing one. The pill is centred against the CARD, not against the card's first row: a group is taller than a condition, so centring is measured off the flex line the card sits on and stays right at every depth and at every number of children. There is no headline: "Any of the following are true..." said what the pill beside it already says, at ten times the width. The sentence survives as the card's accessible NAME through labels.groupLabel, and as the group's description in every announcement.
Delete is in the group's kebab (labels.removeGroup), not inline in the footer. A destructive control in a nested footer is the one thing in the panel a pointer crosses on its way somewhere else.
The card wears an inset RING rather than a border, and that is the whole answer to the trailing controls lining up. A border pushes the content edge inward by a pixel at every level, so the column of kebabs sloped away from the right edge the deeper you read. A ring is painted, not laid out, so a card nested three deep still ends exactly where the panel's content ends. Everything indentation costs is spent on the LEADING edge.
Add filter appends to the ROOT group, a group's own add button appends into that group, and each appends a rule on the first pickable leaf field with NO condition set, then opens the attribute picker on it. A row shows all of its cells at once, so rather than draw a row with a hole in it, a pending row hides its condition and value cells until the attribute is picked. The condition stays unset there for the same reason it does on a chip: the menu that opens next should not arrive with its own answer already highlighted.
Groups nest to any depth over the same tree the chips read. Each level costs the combinator gutter beside the card plus the card's own leading padding, and the gutter is the expensive half and the one that COMPOUNDS.
Below a threshold the group's row WRAPS: the combinator takes the line above the card instead of the column beside it, the level drops from about 76 pixels of indentation to six, and nothing else changes. It is a container query on the list a row actually sits in, not a viewport breakpoint and not a depth budget, because the same panel holds a 650px list at the top level and a 260px one three groups down. The threshold is what a row measures - a 4rem combinator track, four gaps and the trailing pair leave 134px gone before a cell draws anything - so a group whose own list is narrower than 26rem stops charging its children for the gutter.
That is also the answer to extreme depth. Each level shrinks the next list until one falls under the threshold; every level after that costs six pixels, so the indentation converges rather than running off the side, and what deep nesting costs from there is vertical, which is the direction a panel can scroll. Measured on a three-deep query at panel widths from 1104px down to 260px, and at a real 375px phone viewport: the column of kebabs stays on ONE axis at every width, and nothing overflows the body.
A cell sheds decoration before it sheds text. Below 7rem it drops its disclosure caret, below 5rem its attribute type icon: a caret says a list opens here, which the cell being a button already says, and an icon says what kind of attribute this is, which the name says better. The name is the thing that cannot be reconstructed from anything else on the row, and the full path is on the cell's aria-label and title regardless.
One kebab per row, named labels.chipMenu(fieldLabel), holding everything that can be done TO a condition:
The group's kebab (labels.groupMenu) carries Duplicate, Ungroup, the same Move to items, and a destructive Remove group. Both menus are sized w-max min-w-32 max-w-[min(24rem,calc(100vw-2rem))], so an item is as wide as its own longest label and never wraps mid-word - Remove condition group used to render as ...dition group on a second line, and English is the shortest case, so the German and Japanese labels in the i18n example are what this is measured against. The rows are short on purpose (Ungroup, Move to top), which is what makes an 8rem floor and an auto width read as a compact menu instead of a wide one drawn mostly empty; the upper bound is what keeps a long translation inside a narrow viewport. Past the cap the label TRUNCATES rather than wrapping, because a wrapped row changes height and moves every row under it - including the destructive one - out from under the pointer. Each label is a span with min-w-0 and truncate on it, since a flex child's floor is its own content and text-overflow needs a block box to draw an ellipsis in.
Both are FILTER_MENU_CLASS, exported, and menuClassName on the root is merged AFTER it, so a w-* of your own wins through tailwind-merge and reaches all four mount points at once - the chip's kebab, the builder's row and group kebabs, and any menu you compose from FilterRuleMenuItems. The attribute picker's panel is the same arrangement one class along: FILTER_FIELD_PICKER_CLASS is w-auto over a min-w-56 floor, and fieldPickerClassName overrides it in both chromes that mount it.
The panel derives what is unfinished ONCE, from the whole query, through collectFilterIssues. Per row would be the obvious place and it is the wrong one: an empty group is a fact about a group and not about any row inside it, and the summary needs a count no single row can produce.
A group with exactly ONE child is deliberately not an issue: (a) is a, it compiles correctly, and flagging it would put a red ring on the intermediate state of every single nesting gesture. A rule whose field the schema no longer has is not judged at all, because it draws neither an operator cell nor a value cell, and a marker pointing at a control that is not on screen is a marker nobody can act on. It is already flagged as broken in its own way.
These reasons are REPORTED, not DRAWN. collectFilterIssues returns all five so the predicate you compile and the panel read one answer, but the builder no longer marks any of them. Every one describes a row that is HALF BUILT, which is the normal state of a row somebody is filling in: pressing Add filter mints a condition with no value, so flagging it turned the happy path red, and error styling that fires when nothing is wrong is error styling people learn to ignore.
What the builder draws is a field's own validate saying no - a rule the PRODUCT considers wrong, which is the only thing worth interrupting for. A schema with no validators shows no errors at all.
It surfaces in three places:
aria-invalid, a data-invalid styling hook, and the message as aria-description for a screen reader. The visible mark is an error icon INSIDE the value container with the sentence in a tooltip, plus a quiet ring on the cell - a ring and not a border, so a cell turning invalid does not nudge every cell beside it by a pixel.isFilterRuleComplete is the primitive's ONE completeness rule and it is exported, so the predicate you build and the panel read one answer instead of two implementations of it. collectFilterIssues is exported beside it for the whole list, already carrying the nodeId and the column each issue belongs to.There is NO panel-level summary button. A count in the footer was a second place to learn the same thing, phrased as a number, about rows that may be three groups down - and it existed to count the built-in reasons the panel no longer draws. labels.issueSummary survives for the live region and for a consumer building their own.
readOnly does not gate any of it. The flag refuses writes, not reading, and a read-only view of a saved query is exactly where somebody needs to be told why it returns what it does.
Reordering is OPT-IN. Pass reorderable to the bar (or to FiltersAdvanced / FiltersAdvancedPanel directly) and rows grow a drag handle, accept a pointer drop, and move under Alt+ArrowUp / Alt+ArrowDown. Without it there is no handle, the arrow gesture is refused, and the row menu's Move to items are not drawn - all three routes answer to the one switch, so the capability is never off for a pointer and quietly on from a menu.
It is off by default because reordering never changes what a query MEANS: a group is a set joined by one operator, so moving a condition inside its group returns the same rows in the same order. What it costs is a control on every row and a gesture a touch user can start by accident, which is a bad trade for the many builders whose rows are read rather than arranged. Turn it on where the ORDER is part of how people read the query.
Even on, a handle is drawn only where a move could change the tree. The sole row at the root has nowhere to go - every other destination is inside it, and the slots left name the position it already occupies - so it gets none. A nested row always keeps its handle, because it can always move out to the top level.
Reordering never changes depth from the keyboard. Alt+ArrowUp and Alt+ArrowDown move the focused row or group within its own parent; the row menu's Move to top and Move to group N move a condition across groups through the same mutators a pointer drop uses, Wrap in group nests it in a new group, and the group menu's Ungroup dissolves one. The same gesture on an arrow key would otherwise mean two different things depending on where the row happened to sit.
A drop draws two answers, told apart by STYLE:
The insertion marker is a LINE rather than a box, and that follows from the geometry: rects are captured once at pointer-down, so a placeholder that pushed rows aside would leave every frozen hit-target a full row from where its row now appears. A line lives in the gap, which is empty by definition, so the list stays legible for the whole gesture and the picture never disagrees with where a release actually lands.
Dashed is not used for either destination. It was, while the marker was a small pad distinguishable from a group outline by size; once the marker became row-wide, a dashed rule and a dashed card were the same picture at two scales. The group takes a solid ring - a boundary around something that exists - and the accent colour carries the line, which is the one place accent belongs, since a 2px rule in a neutral reads as one of the panel's own dividers. All of it is outlines and pseudo-elements: a real border would push every row below it by two pixels on every pointer move.
The carry that follows the pointer is a real CLONE of the row at its own size, anchored so the point under the finger stays the point that was grabbed. It has no border, no ring and no shadow: it already contains the row's own controls, each with its own boundary, so a box around them is a second frame the original never had. An invalid carry takes a destructive ring, the only chrome it ever gains.
One rule as a row. Memoized.
position is a prop and not a subscription on purpose: a row that read the query from context would re-render on every edit anywhere in it, which is the memoization this primitive is built on being given away.
One rule as a chip. Memoized.
The attribute picker, fully controlled so the same picker serves both chromes.
The picker WINDOWS its rows (CascaderVirtualItems), so a 2,000 field level or a deep search over one keeps only the visible slice in the DOM; below the cascader's threshold it renders plain rows and small schemas pay nothing. The option menus deliberately do not window: their lists either page from a server or, under pinSelected, stack selected rows, and that stack needs the whole list mounted to carry the highlight across a live re-pin. The field schema itself is static and local by design, so a REMOTE schema is a custom-picker concern: compose one with toCascaderNodes, re-exported from filters-builder, plus the cascader's own getChildren, and commit through onSelect.
The condition menu, and the step after it: choosing a condition advances this SAME popover to the value editor rather than opening a second one anchored elsewhere. Every open starts on the condition list.
There is deliberately no FilterFieldPopover. A chip's attribute is fixed for its lifetime; the advanced row re-picks with FilterFieldPicker instead.
Renders the resolved editor in a popover anchored to its trigger, holding the draft, for a value the user aims at directly. Returns the trigger alone when the operator takes no value.
The per-rule actions (Duplicate, Negate, Remove) without the trigger that opens them, so a chip's kebab and a row's kebab share one implementation.
The chip row leaves it off because a chip row has nowhere to draw the group the action would create, so the item would appear to do nothing. In the builder it is on, where it is the only way to nest an existing condition without dragging, and the same menu carries Move to top and Move to group N for a rule that already sits in one.
The one accessible list behind the operator menu and every option editor. It is the cascader, configured.
Every user-facing string comes from labels, and operator wording from operatorLabels. They are two surfaces on purpose: chrome copy is translated once per app, while operator wording is routinely reworded per domain without touching anything else. Pass a partial; the merge is SHALLOW, so replacing a function-valued label replaces it whole rather than leaving the default to leak back in for the arguments you did not think about.
<Filters
fields={fields}
labels={{
addFilter: "Filter hinzufügen",
where: "Wo",
and: "und",
or: "oder",
}}
operatorLabels={{ contains: "enthält", is: "ist" }}
/>Two strings are outside FilterLabels on purpose. The boolean editor's "True" and "False" are constants, because the chip's own display spells the same two words and a key read from two places that must agree is one more thing to keep in step. And the attribute picker is a cascader with a labels bridge: its search placeholder, back control, empty state, path separator, branch counts and results announcement all read from FilterLabels, so one labels prop translates it with the rest of the chrome, while the deeper cascader strings it does not mirror are translated through FilterFieldPicker's own labels prop.
Inside children, these are how a custom bar reads and writes the same state the shipped chromes do. useFilterRuleDisplay in particular gives you the same path, operator and value text both chromes render, so a custom chip cannot disagree with a built-in row about how one rule reads.
Two plain helpers ship beside them, so a chrome composed through children draws the locked state exactly as the shipped one does rather than inventing a second answer.
The chip row's arrow keys and the advanced grid's are logical, not physical: under dir="rtl" the forward and backward keys swap. The value check mark inside every menu is pinned with logical properties, so it stays on the inline end without a mirror.
Logged once each, in development only, and never thrown: a schema arriving from a server should degrade to a usable picker rather than blank the page.
The row is a toolbar with a roving tabindex, so it is ONE tab stop no matter how many filters it holds. Keys pressed inside an open popover belong to that popover, so none of these fires while a menu or an editor is up.
The operator menu and every option-backed editor are the cascader run flat, so they inherit its keyboard whole.
The builder keeps ONE tab stop for the whole tree, however deep it goes, which is what stops a builder of six rows from being thirty tab presses deep before the footer.
Vertical movement is by column NAME rather than by position, because rows are ragged: the first row of a group draws no combinator control, an arity: "none" rule draws no value cell, a group draws an add button and no operator, so a positional index would drift one column per ragged row. The columns sit in two BANDS, content (combinator, field, operator, value) and actions (drag, menu, add, remove), and the fallback searches the source cell's own band first, so ArrowDown from a value cell can never land on a group's delete button. Within a band, backward wins a tie.
Each band is walked in the order its CELLS are painted, not in the order the rows appear in the document, and the two stopped being the same thing when the group's controls moved to its footer. A group's row element opens before the rows it holds, while its own grip, kebab and add button now close after them - so a row walk sent ArrowDown backwards up the panel, measured at two of five presses on a three-deep query. Reading the cells instead needs no traversal and no geometry, because the document already holds the answer: a group's footer cells come after its children's and its combinator comes before them. Rows with no cell in the current band are simply not in it, so ArrowDown from a value cell lands on the next VALUE below rather than on a group's footer button a whole card further down.
One key never reaches the builder at all: a menu button owns ArrowDown, which is how every menu button opens, so the row menu opens rather than moving the tab stop down a row.
role="group" elements, one per condition and one per group, with a roving tabindex over their cells. It is deliberately NOT a role="grid": rows sit at four different depths, and a grid whose rows disagree about their column count is one no assistive technology can describe. A row keeps its value cell even when the operator takes no value, holding nothing, because dropping the box would shift the trailing buttons into the value column on that row alone.role="toolbar" named by labels.filtersLabel, with a roving tabindex. Each chip is a role="group" whose accessible name is labels.filterLabel(condition), built from the resolved path, the operator and the value text, so a screen reader hears the whole condition rather than three unrelated buttons.<button> and a direct child of the group, which is what fuses the pill visually and why there is no button nested inside a button anywhere in a chip. The attribute segment is not one of them: it is plain text, because a chip's attribute cannot be changed, and a button that only reads back what it says costs a screen reader user a press for nothing.valueText rather than by its own contents, because the contents are whatever the field chose to draw: a row of avatars, color dots, a "+2" badge. A button whose name is "plus two" tells a screen reader nothing about the two people it stands for.data-incomplete, a dashed outline and labels.incomplete appended to its accessible name. It is kept rather than removed, and left out of flattenFilterConditions, so a rule that filters nothing can neither disappear silently nor pass for one that filters something. The value segment is not rendered before a condition is chosen, and not at all for an arity: "none" operator, so nothing announces an input that cannot be filled.aria-activedescendant navigation, typeahead, RTL keys and its own visually hidden live region. Each list is named after the field it belongs to, so a reader hears "Priority" rather than a generic "Options", and selection is marked with a check in single and multi select alike, drawn in the gutter every style already reserves. The check's color is pinned, because the shared row style repaints descendant icons on the highlighted row and a selection mark is state rather than decoration.searchable: false hides the search field VISUALLY and never removes it: that input owns focus and aria-activedescendant for the list, so removing it would take the whole keyboard with it. Typing still narrows the list, exactly as typing into a native <select> does.aria-hidden mark rather than a separator NODE, and paging and retry are real buttons in the panel footer rather than option rows. A node in either position would join the option ring: counted by typeahead, filtered away by a query, and announced as a row.labels.exclusiveHint to its accessible NAME, because the rule that sets it apart is exactly the decorative aria-hidden mark above. Without the suffix a screen reader hears a row identical to its neighbours and then loses four selections to it, which is the surprise the rule exists to prevent, delivered to the people least able to recover from it. It is said before the press, not after, and it is a text node inside the row rather than an aria-describedby, so it arrives with the label rather than late or not at all. The rows it hides behind a sr-only class and nothing else, so :has([data-slot=filter-menu-exclusive-hint]) is also how you style the row.labels.exclusiveAnnouncement, because nothing else reports it: the row that was pressed keeps its name, the search box keeps its text, focus never moved, and the check marks that vanished are on rows nobody is reading. An ordinary additive pick announces nothing, since the row the user is on says it itself, and so does toggling the exclusive row back off, which clears nothing.readOnly bar stays navigable, which is the whole point of the flag: its mutating controls keep their tab stops and carry aria-disabled rather than the native attribute, exactly as the cascader's commands do, because the ARIA authoring practices ask a toolbar to keep its unavailable controls discoverable and because the builder's roving tab stop would otherwise sit on an element nothing can focus. disabled is the flag that takes the controls out of the tab order.Delete on the last row - ends with focus back on the roving tab stop's cell, then on the first cell in the builder, then on Add filter, which is the one control that exists at every query. A menu restores focus to its trigger on close, and each of those actions unmounts that trigger in the same commit, so the restore lands on nothing. It is guarded three ways, because moving focus unasked is its own bug: it runs only after a committed change, only when the panel held focus going into it, and only when focus actually ended up nowhere. A user who clicks another control keeps it.tabIndex="-1". That covers the mutators and, more importantly, a consumer's own setQuery: a Reset button, a saved view or an undo replaces the whole tree without going through any mutator at all.readOnly bar also has to stay READABLE, which is a second thing. A value control that cannot open its editor is named with the whole list rather than the count standing in for it, so "2 selected" does not become the end of the road, and a refused action never moves the roving tab stop onto something that was not created: an add the boundary turns down mints no id and hands the focus store nothing, because a store pointing at a row that does not exist leaves every cell at tabIndex="-1" and takes Tab away from the one person the flag exists for.labels.countAnnouncement, and a group announces labels.groupAnnouncement instead, because a group's removal takes an unknown number of conditions with it. A reorder announces labels.reorderAnnouncement, since it is the one edit that changes neither the count nor where focus sits.labels.advancedFilter and DESCRIBED by its own rule count, so a reader who merely arrives at a saved query is told what is in it. The count used to reach assistive technology only through the default popover trigger's badge, which meant inline mode said nothing and a consumer-supplied trigger dropped it, and the live region only speaks on a change. In popover mode the popup carries the same name as the panel, because a role="dialog" with no name announces as "dialog"; the trigger's name carries the count as a sentence (labels.countAnnouncement) while the badge itself is aria-hidden, since a bare numeral read out after a label says what it counts to nobody. Under readOnly the panel's description carries labels.readOnly as well, which is the same sentence the visible line shows: aria-readonly is not allowed on role="group", and a description is both legal and spoken on entry."use client"

Four overrides, and every one of them undoes the same bug.
`DataGridPagination` goes single row at `sm`, which is a VIEWPORT
query rather than a container one, so inside a card narrower than
640px it stacks its three parts however wide the card itself is:
page buttons, then the record range, then rows-per-page, reversed by
`order-*` and about 140px tall. In a preview frame that is most of
the height this example has to spend, and a pager nobody can see
cannot show that the query changed the page count.
flex-row py-0 the parent's own axis and padding. Plain
utilities, because the primitive merges this
className through `cn`, so tailwind-merge drops
the `flex-col` and `py-2.5` it replaces.
**:order-none! source order at every depth. Two levels need
it, the two halves of the bar and the range
against the buttons inside the right half.
*:py-0! the two halves' own stacking padding.
*:last:flex-row! the right half, which stacks internally too.
The three `!` are load-bearing: those classes live on the
primitive's own children, out of tailwind-merge's reach, so nothing
else can win against them.
`flex-wrap` is left alone deliberately, so this degrades rather than
breaks: on a genuinely narrow phone the two halves wrap to two rows
instead of forcing a 400px row into 375px.

FOUR chips, and the fourth is the last one that fits.
Five editors are on show, and seeding one chip each is the obvious
thing: every editor would then be one press away. It does not fit, and
the way it fails is worse than the click it saves. The bar is a wrapping
row whose chips live in an inner toolbar, and a flex child that wraps
internally claims the full width of its line, so the moment the fifth
chip goes to a second row the toolbar owns BOTH rows and pushes Add
filter and Clear onto a third - the trigger at the far left, Clear at
the far right, a thousand pixels of nothing between them.
Measured at the width a catalog card gives this bar (1128px), the five
chips run 1172 to 1336 depending on the style against a budget of 977 to
1036. No arrangement of five fits and no wording closes a 300px gap, so
the count is the thing that gives. Two of the five drops leave a row that
fits; this one clears sera by 64px where dropping Channel clears it by
15, and it costs the least besides, because Permissions drew the same
`PickedLabels` display the Channel chip already shows - and shows better,
since Channel carries the overflow count too. Its editor is reachable
from Add filter like any other field.

* The aggregate strip, and the reason this example took its grid from the

*
* A builder is the chrome you reach for when the question is complicated, and
* a complicated question deserves an answer with a number in it. Sorting is
* the same in both chromes and proves nothing about the query; a total that
* moves the moment a group's combinator flips is the shortest honest proof
* that the tree reached the data.
*
* The label spans the three text columns, so each number sits under the
* column it sums, and the two totals carry the same right alignment their
* columns do - a total that did not would be the one number on screen not
* lining up with the figures it adds.
*
* A foot cell is not a body cell, so `cellClassName` does not reach it and
* the two gutter columns have to be given theirs by hand. The spanning label
* is the leading cell here even though it covers three columns, which is why
* it takes the start gutter rather than the account column's own foot cell -
* there isn't one.

bar's 10px of padding with the style's full card spacing.
The utility wins on layer order, not specificity: the per-style card

Four overrides, and every one of them undoes the same bug.
`DataGridPagination` goes single row at `sm`, which is a VIEWPORT
query rather than a container one, so inside a card narrower than
640px it stacks its three parts however wide the card itself is:
page buttons, then the record range, then rows-per-page, reversed by
`order-*` and about 140px tall. In a preview frame that is most of
the height this example has to spend, and a pager nobody can see
cannot show that the query changed the page count.
flex-row py-0 the parent's own axis and padding. Plain
utilities, because the primitive merges this
className through `cn`, so tailwind-merge drops
the `flex-col` and `py-2.5` it replaces.
**:order-none! source order at every depth. Two levels need
it, the two halves of the bar and the range
against the buttons inside the right half.
*:py-0! the two halves' own stacking padding.
*:last:flex-row! the right half, which stacks internally too.
The three `!` are load-bearing: those classes live on the
primitive's own children, out of tailwind-merge's reach, so nothing
else can win against them.
`flex-wrap` is left alone deliberately, so this degrades rather than
breaks: on a genuinely narrow phone the two halves wrap to two rows
instead of forcing a 400px row into 375px.

Stacked, not beside the output, and that is a measurement rather than a
preference. A condition is five cells wide and every nesting level pays
the leading combinator column, the card border and the indent again, so
each depth costs roughly 88px off the row. At depth two a 34rem column
leaves the attribute cell around 45px of text and the row reads
"# | i. | 8". The builder takes the full width and the output goes
underneath it, which is the only arrangement where this example's own
"Nest two levels" button produces something legible.

{/*
The surface is the CONSUMER's, and it is a WRAPPER - the ordinary thing,
written the ordinary way. The builder owns everything inside itself and
nothing about the box it sits in, so the box is a `Card` here and could
be a Frame, a bare section, or nothing at all.
The primitive used to take this element as an `advancedSurface` prop and
render itself AS it. That worked, and a wrapper buys the same result
with no seam to explain: no rule about which way `className` merges, and
no list of the props the panel has to keep stamping on an element it does
not own. Inline the panel pads itself by nothing, so the Card's own
padding is the only padding, which is what makes this read as one box.

ONE output, not two. A group is a parenthesised list joined by ONE
combinator, so a walk needs no precedence rules to guess at: bracket
each nested group and the tree reads back exactly as it was built,
resolved through each field's `column`. That walk is what this example
is for. The raw `JSON.stringify(query)` panel that used to sit beside
it was debugger output, not a demonstration: it restated the same tree
in a shape nobody reads, and it halved the width the readable half had.
