## Best for

A report builder that adds table columns several at a time, counting them in the trigger and listing each as a removable chip below

## Agent notes

- `ColumnChips` reads `useCascaderSelection`, so it has to render inside `Cascader`

## When not to use

- Toggling which fields an existing table displays, in place: use [Data Grid](https://reui.io/components/data-grid.md) (`get_component("data-grid")`)

## Install

```bash
npx shadcn@latest add @reui/c-cascader-17
```

## About Shadcn Cascader

### When to use

- Form fields that commit one value from a nested tree, such as a category, region, file or department
- Picking several nodes at once, such as permissions, report columns or shipping zones with cascading checks
- Deep or large hierarchies as Miller columns, an expanding tree, an inline panel or levels fetched on demand

### When not to use

- A short flat list of options with no nesting: use [Select](https://reui.io/components/select.md) (`get_component("select")`)
- A folder hierarchy browsed on the page rather than picked into a form field: use [Tree](https://reui.io/components/tree.md) (`get_component("tree")`)
- A table of records whose cells are edited in place and saved together: use the [Editing blocks](https://reui.io/blocks/data-grid/editing.md)

### Agent notes

- Parts live in separate files with no index: `CascaderItems` comes from `cascader-item`, while `CascaderInput` and `CascaderValue` come from `cascader-nav`
- Give every node a `value` that is unique across the whole tree, not only within its level; a repeated `value` silently drops the later row

Every ReUI item has a twin like this one; the index is https://reui.io/llms.txt. Agents with the ReUI MCP (https://reui.io/docs/mcp) get the same guidance from the getters named above.
