Command.
Find an action without searching the whole interface.
Base UI Combobox owns filtering, highlighted options and selection. Command.Root defaults to inline, logically open and automatic highlighting, following Base UI’s inline-list contract. Compose the same command surface inside Command.Dialog for modal focus containment and return focus.

Composition
AnatomyBase UI Combobox owns filtering, highlighted options and selection. Command.Root defaults to inline, logically open and automatic highlighting, following Base UI’s inline-list contract. Compose the same command surface inside Command.Dialog for modal focus containment and return focus.
Command.Root (inline/open, items, onValueChange)
├── Command.Input (aria-label)
├── Command.List → Command.Item
└── Command.Empty
Optional modal: Command.Dialog parts surround the comboboxA place to start
UsageImport the stylesheet once at your application root. This complete example reflects the properties selected above.

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.
CommandRoot
| Prop | Type / description | Default |
|---|---|---|
inline | booleanKeep the command list inline. | true |
open | booleanControlled visibility; defaults to true for the inline command list. | — |
autoHighlight | booleanHighlight the first matching command. | true |
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-color-background-surface | 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
AccessibilityProvide visible labels and meaningful names. Preserve native semantics, selected/disabled state and visible focus. Target WCAG 2.2 AA; full contrast, assistive-technology and platform verification remains pending.
Target: WCAG 2.2 AA. Automated tests cover selected behavior; manual screen-reader, contrast, and zoom validation remain part of the release checklist.
