Combobox.
Find a choice without losing your place.
Root retains generic item/value inference, filtering and selection. Name the input, trigger and clear control. Put popup-only empty/status content inside Popup and provide itemToStringLabel for object-valued items.

The finer details
API referenceGenerated from Dixy’s local TypeScript interfaces. Native and Base UI Combobox props are forwarded; this table covers the options Dixy adds.
ComboboxInput
| Prop | Type / description | Default |
|---|---|---|
size | "sm" | "md" | "lg"Component proportions; preserves the shared interaction target. | md |
variant | "soft" | "outline"Visual emphasis; behavioral state remains primitive-owned. | outline |
radius | "none" | "sm" | "md" | "lg" | "full"Contextual rounding; panels cap full rounding to preserve content. | Theme.radius |
material | "matte" | "glossy" | "soft" | "metal" | "paper"Optional static finish; import materials.css. | Theme.material |

Built from the same foundations
Styling tokensChange Theme settings above to compare appearance, accent, neutral, radius, spacing density, motion and direction. Override component aliases on a Theme root so custom properties follow portaled content too. The wrapper merges className, style, refs and render composition with its owning primitive.
| Token | Purpose |
|---|---|
--dixy-primitive-gap | The component-specific starting point. |
--dixy-font-label-md | Control label font and line height; body roles remain readable in text inputs. |
--dixy-color-background-selected | Selected surfaces use semantic color across appearances. |
--dixy-color-border-focus | Focus indication remains visible independently of shadows. |
--dixy-spacing-inset-sm | Density-aware component padding. |
--dixy-motion-transition-feedback | Short state feedback, reduced by the inherited motion setting. |
Consider everyone
AccessibilityBase UI owns filtering, highlight and selection. Preserve generic item types and keep empty results explicit. Provide meaningful names and verify the complete interaction with a keyboard. Color alone must not communicate state.
Target: WCAG 2.2 AA. Automated tests cover selected behavior; manual screen-reader, contrast, and zoom validation remain part of the release checklist.
Build it. Then understand it.
Base UI owns filtering, highlight and selection. Preserve generic item types and keep empty results explicit. Component aliases reference Dixy semantic tokens; refs, events and render composition are forwarded unchanged. Visual settings follow Dixy shirt sizes, contextual radii and semantic tokens where applicable. Static finishes are optional, and reduced motion is immediate. Base UI keeps refs, state, events, keyboard and presence; this implementation pass does not establish WCAG conformance.
