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 |
|---|---|---|---|
| label / children | string / media content | required | Supplies a visible, accessible name and decorative media. Do not nest interactive controls in the thumbnail button. |
| selected / order | boolean / positive integer | false / omitted | Shows pressed selection and an optional visible ordinal. Selection stays application-owned. |
| mediaId | string | required in Astro / media-id in Elements | Identifies ui:media-selection-request detail { id, selected }. React uses the existing onClick callback. |
| state / stateLabel / disabled | "ready" | "loading" | "error" / string / boolean | "ready" / English fallback / false | Loading and failed media retain framing and disable selection. Localize stateLabel for non-ready items. |
| 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. |
