Add the glass prop to apply the shared blur, saturation, border, and highlight tokens. Glass reads best over vivid content, so place the surface above imagery or color.

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 |
|---|---|---|---|
| glass | boolean | "subtle" | "strong" | false | Applies the tokenized liquid-glass surface treatment with backdrop-filter fallbacks; "subtle" and "strong" adjust the fill intensity. |
| disabled | boolean | false | Disables month navigation, date selection, and the hidden form input. |
| max | YYYY-MM-DD string | - | Disables dates after the inclusive maximum date. |
| min | YYYY-MM-DD string | - | Disables dates before the inclusive minimum date. |
| month | YYYY-MM string | current or selected month | Sets the initially visible month. |
| name | string | - | Sets the name of the hidden input that stores the selected ISO date. |
| value | YYYY-MM-DD string | "" | Sets the selected date and hidden input value. |
| 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.
