First install and activate one skin. Core deliberately contains no visual token defaults.

The Control UI source installs this primitive from src/registry/sources/control-ui/ui/trigger-menu.tsx. Install it on its own with the command above, or inspect the source below.

Registry command

npx shadcn@latest add https://control-ui.dev/r/trigger-menu.json

See registry manifest

Knobs

Typed custom properties the recipe paints with. Set one on the root — style, a utility class, or a skin — and every slot inherits it.
