Lumen-specific props and runtime attributes for the Astro primitive. Use the framework differences above and the copyable examples for React composition and Elements attributes; the public adapter types define their supported contracts.
| Attribute | Values | Default | Description |
|---|---|---|---|
| options | Array<string | { label, value, disabled?, section? }> | [] | Defines options and optional accessible sections. |
| value | string | string[] | - | Controls the selected value or values. |
| multiple | boolean | false | Allows more than one selected value while preserving native form submission. |
| loading | boolean | false | Marks the collection busy and disables selection while options load. |
| emptyMessage | string | "No options available" | Labels the empty collection state. |
| selectionFollowsFocus | boolean | false | Selects each enabled option as keyboard focus moves instead of waiting for Space or Enter. |
| class, className | string | "" | Merges custom classes with the generated ui-* root classes. |
| ...native attributes | HTML attributes | - | Forwards standard attributes to the root element unless the component consumes them. |
Keyboard interactions
Keyboard behavior provided by the Astro UIPrimitives runtime for this component.
| Key | Action |

| Home / End | Moves to the first or last enabled option. |
| Space / Enter | Selects or toggles the active option. |
