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 and ui-* class contract.

Glass

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.

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.
role	ARIA role	"tree"	Generated tree role for the root element.
aria-expanded, aria-level	ARIA attributes	-	Use on child items to indicate nested tree structure.
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.
