Menubar.

A row of menus like a desktop app's menu bar, with shortcuts, checkbox and radio items and submenus.

Installation#

With the CLI

$npx lanterncn add menubar

This also installs the Lantern theme and any Lantern UI components it depends on. The shadcn CLI works directly too: npx shadcn@latest add httptim/lantern-ui/menubar. See Installation if your project is not set up yet.

Manually

  1. Install the dependencies

    npm install radix-ui lucide-react

  2. Copy the source into your project

    components/ui/menubar.tsx
    "use client";

  3. Update the import paths to match your project

    The source imports cn from @/lib/utils.

Usage#

import {
  Menubar,
  MenubarMenu,
  MenubarCheckboxItem,
  MenubarContent,
  MenubarGroup,
  MenubarItem,
  MenubarLabel,
  MenubarPortal,
  MenubarRadioGroup,
  MenubarRadioItem,
  MenubarSeparator,
  MenubarShortcut,
  MenubarSub,
  MenubarSubContent,
  MenubarSubTrigger,
  MenubarTrigger,
} from "@/components/ui/menubar";
<Menubar>
  <MenubarMenu>
    <MenubarTrigger>File</MenubarTrigger>
    <MenubarContent>
      <MenubarItem>New program <MenubarShortcut>Ctrl N</MenubarShortcut></MenubarItem>
      <MenubarSeparator />
      <MenubarItem>Save</MenubarItem>
    </MenubarContent>
  </MenubarMenu>
</Menubar>

Once a menu is open, Left and Right arrows move between menus and hovering another trigger switches to it. Item parts share the Dropdown Menu API.
