A composable dropdown menu built on Radix UI primitives, with support for grouped items, labels, separators, keyboard shortcuts, disabled actions, and nested submenus. The registry example uses an outlined Button as the trigger and styled menu content.

Installation

pnpm dlx shadcn@latest add @bundui/dropdown-menu

Requires @bundui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { Button } from "@/components/ui/button";import {  DropdownMenu,  DropdownMenuContent,  DropdownMenuItem,  DropdownMenuTrigger,} from "@/components/ui/dropdown-menu";export default function Example() {  return (    <DropdownMenu>      <DropdownMenuTrigger asChild>        <Button variant="outline">Actions</Button>      </DropdownMenuTrigger>      <DropdownMenuContent align="start">        <DropdownMenuItem>Rename</DropdownMenuItem>        <DropdownMenuItem>Duplicate</DropdownMenuItem>        <DropdownMenuItem disabled>Delete</DropdownMenuItem>      </DropdownMenuContent>    </DropdownMenu>  );}
  • Use for contextual actions associated with a button, control, or page area.
  • Use for account menus, resource actions, navigation options, and command lists.
  • Use nested submenus when a flat list would become too long or difficult to scan.
  • Use DropdownMenuShortcut to communicate available keyboard combinations alongside actions.

Examples

Account actions

A labeled account menu with keyboard shortcuts and a disabled API item.

account-actions.tsx
import { Button } from "@/components/ui/button";import {  DropdownMenu,  DropdownMenuContent,  DropdownMenuItem,  DropdownMenuLabel,  DropdownMenuSeparator,  DropdownMenuShortcut,  DropdownMenuTrigger,} from "@/components/ui/dropdown-menu";export default function AccountMenu() {  return (    <DropdownMenu>      <DropdownMenuTrigger asChild>        <Button variant="outline">My account</Button>      </DropdownMenuTrigger>      <DropdownMenuContent align="end">        <DropdownMenuLabel>Account</DropdownMenuLabel>        <DropdownMenuItem>          Profile          <DropdownMenuShortcut>⇧⌘P</DropdownMenuShortcut>        </DropdownMenuItem>        <DropdownMenuItem>          Settings          <DropdownMenuShortcut>⌘S</DropdownMenuShortcut>        </DropdownMenuItem>        <DropdownMenuSeparator />        <DropdownMenuItem disabled>API access</DropdownMenuItem>        <DropdownMenuItem>Sign out</DropdownMenuItem>      </DropdownMenuContent>    </DropdownMenu>  );}

Accessibility

  • Use a visible, descriptive trigger label, or provide an accessible aria-label when the trigger contains only an icon.
  • Prefer DropdownMenuTrigger with asChild so the actual interactive child remains the semantic button or control.
  • Radix manages menu roles, focus movement, keyboard navigation, typeahead, Escape handling, and outside-interaction behavior.
  • Use DropdownMenuItem for actions and provide clear, concise labels; use disabled for unavailable actions rather than removing important context.
  • Keep DropdownMenuShortcut supplemental: do not rely on shortcut text as the only way to discover or operate an action.
  • Ensure custom trigger and item styling preserves visible focus indicators and sufficient color contrast.
  • Use DropdownMenuLabel for grouping context, not as an interactive control.
