Usage

import {
  DropdownMenu,
  DropdownMenuContent,
  DropdownMenuItem,
  DropdownMenuSeparator,
  DropdownMenuTrigger,
} from "@/components/ui/dropdown-menu"

<DropdownMenu>
  <DropdownMenuTrigger asChild>
    <Button>Actions</Button>
  </DropdownMenuTrigger>
  <DropdownMenuContent>
    <DropdownMenuItem icon={<Copy />} shortcut="⌘C">Copy URL</DropdownMenuItem>
    <DropdownMenuSeparator />
    <DropdownMenuItem variant="danger">Delete project</DropdownMenuItem>
  </DropdownMenuContent>
</DropdownMenu>

Examples

Account menu

Without asChild the trigger renders a plain button you can style. Labels take any content.

Checkbox and radio items

Call event.preventDefault() in onSelect to flip several options without the menu closing.

Nested submenus

Submenus open on hover after a short delay, or with ArrowRight. Moving diagonally toward an open submenu won't close it.

API reference

DropdownMenu

Holds the open state. Renders no element of its own.

PropTypeDefault
openboolean

Controlled open state.

None
defaultOpenboolean

Initial state when uncontrolled.

false
onOpenChange(open: boolean) => void

PropTypeDefault
asChildboolean

false

DropdownMenuContent

The menu panel, portaled and positioned with floating-ui. It flips and shifts to stay on screen and scrolls when it's taller than the space. Inside a modal dialog it portals into the dialog. --menu-trigger-width holds the trigger's width, so className="w-[var(--menu-trigger-width)]" matches it.

false

Accessibility

  • Follows the WAI-ARIA menu button pattern: the trigger has aria-haspopup="menu" and aria-expanded, items are menuitem, menuitemcheckbox or menuitemradio with real DOM focus.
  • Enter, Space and ArrowDown on the trigger open the menu on the first item; ArrowUp opens it on the last. A mouse opens it on press, so press, drag and release selects.
  • Arrow keys move and skip disabled items, Home and End jump, and typing letters jumps to a matching item. Pressing the same letter again cycles.
  • Enter or Space selects. ArrowRight or Enter opens a submenu on its first item and ArrowLeft closes it. Escape closes one level at a time.
  • Tab closes the menu and moves on from the trigger. Escape, a selection and Tab return focus to the trigger.
  • When the trigger sits in a modal Dialog, the menu renders inside the dialog so it isn't made inert.
