Shadcn Cascader Controlled State

Controlled path, value, query and open state. Built by composing Button, Cascader, Cascader Item, Cascader Nav, Cascader Types. A free, open source shadcn cascader example you can install with npx shadcn@latest add @reui/c-cascader-9 and edit as your own code.

External buttons jump the panel to a level, reset it to the root and clear the selection, with all four controlled props printed under the control.

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Free to install.

Best for: A restaurant menu where outside code drives the open level and search text, and each commit reports its reason and full path

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 the Select component
A folder hierarchy browsed on the page rather than picked into a form field: use the Tree component
A table of records whose cells are edited in place and saved together: use the Editing blocks

Agent notes

Writing value from outside never fires onValueChange, so the Clear selection button sets lastChange by hand
goTo also sets open, because a path written while the popup is closed renders nothing
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
