Usage
usage.tsx
import { Combobox, ComboboxInput } from "@/registry/bases/radix/ui/combobox";<Combobox> <ComboboxInput placeholder="Select trick..." /></Combobox>- When users need to choose one item from a searchable list.
- When basic substring filtering is insufficient and results should match multiple fields with fuzzy ranking.
- When option labels and internal values should both be searchable.
- When a combobox needs a clear no-results state.

PropTypeDefaultDescription
propsnull—The `ComboboxCustomFilterDemo` example component accepts no props. Its internal selected value is controlled with React state.
Accessibility
- Keep the visible `ComboboxLabel` so the input has an associated human-readable label; the placeholder should not be the only label.
- Use descriptive visible text for every `ComboboxItem`; the demo pairs each stable value with a readable trick name.
- Retain the explicit `ComboboxEmpty` message so users receive feedback when filtering returns no options.
- The chevron is decorative in this example because it has no accessible text; the combobox input and trigger behavior are provided by the installed combobox component.
