Framework example
Choose Astro, React, or Elements to compare native usage against the shared visual output. Each example assumes the framework-level setup is already complete.
Framework usage
Switch targets to compare the adapter code. The preview stays visually stable because all three packages share the same tokens andui-* class contract.---

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. |
| data-ui-trigger | boolean attribute | - | Marks the child trigger that opens and closes the adjacent disclosure panel. |
| 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. |
