Usage

usage.tsx
import {  Menubar,  MenubarContent,  MenubarItem,  MenubarMenu,  MenubarShortcut,  MenubarSub,  MenubarSubContent,  MenubarSubTrigger,  MenubarTrigger,} from "@/components/ui/8bit/menubar";export function AppMenubar() {  return (    <Menubar>      <MenubarMenu>        <MenubarTrigger>File</MenubarTrigger>        <MenubarContent>          <MenubarItem>            New project <MenubarShortcut>⌘N</MenubarShortcut>          </MenubarItem>          <MenubarSub>            <MenubarSubTrigger>Export</MenubarSubTrigger>            <MenubarSubContent>              <MenubarItem>Export as PNG</MenubarItem>              <MenubarItem>Export as SVG</MenubarItem>            </MenubarSubContent>          </MenubarSub>        </MenubarContent>      </MenubarMenu>    </Menubar>  );}
  • Provide a desktop-style navigation bar with several related menus.
  • Group commands such as File, Edit, and View in a compact interface.
  • Offer nested commands, toggles, or mutually exclusive options in a retro or pixel-art UI.
  • Use when users benefit from the keyboard-accessible menu interactions supplied by Radix.

API reference

PropTypeDefaultDescription
MenubarReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.Root>—Root menubar props from Radix, including its `className` and menu-state props. Forwards its ref. The supplied `className` is applied to both the decorative wrapper and the Radix root; the retro font is applied by the component.
MenubarMenuReact.ComponentProps<typeof MenubarPrimitive.Menu>—Props forwarded to the Radix menu grouping primitive.
MenubarGroupReact.ComponentProps<typeof MenubarPrimitive.Group>—Props forwarded to the Radix group primitive.
MenubarPortalReact.ComponentProps<typeof MenubarPrimitive.Portal>—Props forwarded to the Radix portal primitive.
MenubarRadioGroupReact.ComponentProps<typeof MenubarPrimitive.RadioGroup>—Props forwarded to the Radix radio-group primitive.
MenubarSubReact.ComponentProps<typeof MenubarPrimitive.Sub>—Props forwarded to the Radix submenu primitive; the component adds `data-slot="menubar-sub"`.
MenubarTriggerReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.Trigger>—Radix trigger props, including `className`; forwards its ref.
MenubarContentReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.Content>—Radix content props, including `className`; forwards its ref and renders the content inside a Radix portal. Defaults `align` to `"start"`, `alignOffset` to `-4`, and `sideOffset` to `8`.
MenubarSubTriggerReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.SubTrigger> & { inset?: boolean }—Radix submenu-trigger props plus optional `inset`, which adds left padding. Forwards its ref and renders a pixel-style right chevron after its children.
MenubarSubContentReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.SubContent>—Radix submenu-content props, including `className`; forwards its ref.
MenubarItemReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.Item> & { inset?: boolean }—Radix item props plus optional `inset`, which adds left padding. Forwards its ref.
MenubarCheckboxItemReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.CheckboxItem>—Radix checkbox-item props, including its checked-state props; forwards its ref and renders a pixel-style check indicator.
MenubarRadioItemReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.RadioItem>—Radix radio-item props; forwards its ref and renders a circular selection indicator.
MenubarLabelReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.Label> & { inset?: boolean }—Radix label props plus optional `inset`, which adds left padding. Forwards its ref.
MenubarSeparatorReact.ComponentPropsWithoutRef<typeof MenubarPrimitive.Separator>—Radix separator props, including `className`; forwards its ref.
MenubarShortcutReact.HTMLAttributes<HTMLSpanElement>—Standard span HTML attributes. Renders shortcut text in a right-aligned, muted style.

Accessibility

  • Radix Menubar primitives provide the menu interaction and keyboard behavior; retain their expected component nesting when composing the exported parts.
  • Give each MenubarTrigger a clear accessible name, and use descriptive text for menu items and submenu triggers.
  • Use MenubarCheckboxItem and MenubarRadioGroup with their Radix checked/value state props so selection state is conveyed, not indicated by styling alone.
  • MenubarShortcut is visual helper text in a span; do not rely on it as the only accessible label or description of an action.
