shadcn/ui DropdownMenu root — the state machine behind a menu.

The element that opens the menu. Pass asChild to project the trigger behaviour onto your own button instead of rendering a nested one.

Portal that lifts the menu out of the DOM position where it was declared and mounts it at the document root.

The menu surface itself — portalled, positioned against the trigger, and styled on the Immersion Cinema panel tokens shared with the dialog and the outline sidebar.

A plain action or navigation entry, exposed as menuitem.

Groups DropdownMenuRadioItems into one single-choice set. Exactly one item is checked at a time, reflecting value.

One option in a DropdownMenuRadioGroup, exposed as menuitemradio with its checked state in aria-checked.

Renders its children only while the surrounding item is checked. Place it inside a DropdownMenuRadioItem to mark the current choice.
