Add Combobox

Base UI / canonicalnpx shadcn@latest add https://gummyui.dev/r/gummy-combobox.json

Canonical dependency: @base-ui/react. Combobox remains Base-only because Radix does not publish a Combobox primitive. Registry dependencies are resolved automatically.

Behavior contract

Semantics before surface

Semantics

Base UI combobox, listbox, options, empty state, and form value.

Keyboard

Typing filters; arrows move options; Enter selects; Escape closes.

System support

Light and dark themes, logical RTL layout, reduced motion, responsive content, and forwarded public refs.

Prop contracts

Each exported part accepts the underlying native, Base UI, or documented Radix prop contract. Inspect the selected source below for exact generic types.

Troubleshooting

Check behavior before surface.

If the material is missing, confirm the registry-installed shared and component CSS files are imported once.
If interaction differs, preserve this contract: Typing filters; arrows move options; Enter selects; Escape closes.
If assistive output differs, preserve this semantic foundation: Base UI combobox, listbox, options, empty state, and form value.
If dark, RTL, or reduced-motion behavior is missing, verify the nearest theme, direction, and media-query boundaries rather than adding page-local overrides.

Implementation decisions

When to use Combobox

Use a combobox when customers need to search or choose from a substantial option set; a native select is usually clearer for a short stable list. Keep the typed value, highlighted option, and committed selection distinct. Announce result counts and empty states without excessive chatter. Test free text, exact matches, long results, async failure, touch input, escape, blur, and reopening after a selection.
