Choose the package for your runtime. All adapters share the Lumen stylesheet. Use the matching registry command when you want a local wrapper for that framework.

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.

</div>API reference
Lumen-specific props and runtime attributes for the Astro primitive. React props follow the same names; Elements use equivalent kebab-case attributes where custom elements expose them.
| 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. |
| value, defaultValue | ISO date string (YYYY-MM-DD) | - | Sets the selected date while the trigger shows a localized, human-readable value. |
| min, max | ISO date string (YYYY-MM-DD) | - | Disables dates and month navigation outside the allowed range. |
| placeholder | string | "Choose a date" | Labels the trigger before a date is selected. |
| UIPrimitives | Astro runtime | required | Enhances the form-backed input into the custom Calendar popover. React and registered Elements provide equivalent behavior. |
| 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 |
|---|---|
| Enter, Space on trigger | Open the calendar popover. |
| ArrowDown on trigger | Open the calendar and move focus to the selected day, today, or first available day. |
| Arrow keys in calendar | Move focus by day or week without opening a browser-native date picker. |
| PageDown, PageUp in calendar | Move to the same date in the next or previous month. |
| Enter, Space on a day | Select the focused date, close the popover, and return focus to the trigger. |
| Escape | Close the calendar without changing the value and return focus to the trigger. |
