Choose your target

Add this component

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.

bash@santi020k/lumen-astro
pnpm add @santi020k/lumen-astro
pnpm add @santi020k/lumen-astro
bashAstro wrapper
lumen add Tree
lumen add Tree

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.

AttributeValuesDefaultDescription

roleARIA role"tree"Generated tree role for the root element.
aria-expanded, aria-levelARIA attributes-Use on child items to indicate nested tree structure.
class, classNamestring""Merges custom classes with the generated ui-* root classes.
...native attributesHTML attributes-Forwards standard attributes to the root element unless the component consumes them.
