Examples

Nested navigation

You can nest menus to create a more complex navigation structure. It is important to use the placement prop to ensure the submenu is displayed in the correct position. The best practice is to use the right top placement for the submenu.

<MenuTrigger>
  <Button aria-label="Menu">Menu</Button>
  <Menu>
    <MenuItem>Edit</MenuItem>
    <MenuItem>Duplicate</MenuItem>
    <SubmenuTrigger>
      <MenuItem>Submenu</MenuItem>
      <Menu placement="right top">
        <MenuItem>Edit</MenuItem>
        <MenuItem>Duplicate</MenuItem>
        <MenuItem>Rename</MenuItem>
        <MenuSeparator />
        <MenuItem>Share</MenuItem>
        <MenuItem>Move</MenuItem>
        <MenuSeparator />
        <MenuItem iconStart={<RiChat1Line />}>Feedback</MenuItem>
      </Menu>
    </SubmenuTrigger>
  </Menu>
</MenuTrigger>

With icons

You can use the iconStart prop to add an icon to the menu item.

<MenuTrigger>
  <Button aria-label="Menu">Menu</Button>
  <Menu>
    <MenuItem iconStart={<RiFileCopyLine />}>Copy</MenuItem>
    <MenuItem iconStart={<RiEdit2Line />}>Rename</MenuItem>
    <MenuItem iconStart={<RiChat1Line />}>Send feedback</MenuItem>
  </Menu>
</MenuTrigger>

With links

You can use the href prop to add a link to the menu item. This is using our router provider under the hood to work for both internal and external links.

<MenuTrigger>
  <Button aria-label="Menu">Menu</Button>
  <Menu>
    <MenuItem href="/home">Internal link</MenuItem>
    <MenuItem href="https://www.google.com" target="_blank">
      External link
    </MenuItem>
    <MenuItem href="mailto:test@test.com">Email link</MenuItem>
  </Menu>
</MenuTrigger>

With sections

You can use the MenuSection component to add a section to the menu.

<MenuTrigger>
  <Button aria-label="Menu">Menu</Button>
  <Menu>
    <MenuSection title="My Account">
      <MenuItem iconStart={<RiUserLine />}>Profile</MenuItem>
      <MenuItem iconStart={<RiSettingsLine />}>Settings</MenuItem>
    </MenuSection>
    <MenuSection title="Support">
      <MenuItem iconStart={<RiQuestionLine />}>Help Center</MenuItem>
      <MenuItem iconStart={<RiCustomerService2Line />}>
        Contact Support
      </MenuItem>
      <MenuItem iconStart={<RiChat1Line />}>Feedback</MenuItem>
    </MenuSection>
  </Menu>
</MenuTrigger>

With separators

You can use the MenuSeparator component to add a separator to the menu.

<MenuTrigger>
  <Button aria-label="Menu">Menu</Button>
  <Menu>
    <MenuItem>Edit</MenuItem>
    <MenuItem>Duplicate</MenuItem>
    <MenuItem>Rename</MenuItem>
    <MenuSeparator />
    <MenuItem>Share</MenuItem>
    <MenuItem>Move</MenuItem>
    <MenuSeparator />
    <MenuItem iconStart={<RiChat1Line />}>Feedback</MenuItem>
  </Menu>
</MenuTrigger>

With autocomplete

You can use the MenuAutocomplete component to add a autocomplete to the menu.

<MenuTrigger isOpen>
  <Button aria-label="Menu">Menu</Button>
  <MenuAutocomplete placeholder="Filter">
    <MenuItem>Create new file...</MenuItem>
    <MenuItem>Create new folder...</MenuItem>
    <MenuItem>Assign to...</MenuItem>
    <MenuItem>Assign to me</MenuItem>
    <MenuItem>Change status...</MenuItem>
    <MenuItem>Change priority...</MenuItem>
    <MenuItem>Add label...</MenuItem>
    <MenuItem>Remove label...</MenuItem>
  </MenuAutocomplete>
</MenuTrigger>

With list box

You can use the MenuListBox component to add a list box to the menu.

const [selected, setSelected] = useState<Selection>(
  new Set(['blueberry']),
);

<Flex direction="column" gap="2" align="start">
  <Text>Selected: {Array.from(selected).join(', ')}</Text>
  <MenuTrigger>
    <Button aria-label="Menu">Menu</Button>
    <MenuAutocompleteListbox
      selectedKeys={selected}
      onSelectionChange={setSelected}
    >
      {options.map(option => (
        <MenuListBoxItem key={option.value} id={option.value}>
          {option.label}
        </MenuListBoxItem>
      ))}
    </MenuAutocompleteListbox>
  </MenuTrigger>
</Flex>

With list box with multiple selection

You can use the MenuListBox component to add a list box to the menu. You can also use the selectionMode prop to allow multiple selection.

const [selected, setSelected] = useState<Selection>(
  new Set(['blueberry', 'cherry']),
);

<Flex direction="column" gap="2" align="start">
  <Text>Selected: {Array.from(selected).join(', ')}</Text>
  <MenuTrigger>
    <Button aria-label="Menu">Menu</Button>
    <MenuAutocompleteListbox
      selectionMode="multiple"
      selectedKeys={selected}
      onSelectionChange={setSelected}
    >
      {options.map(option => (
        <MenuListBoxItem key={option.value} id={option.value}>
          {option.label}
        </MenuListBoxItem>
      ))}
    </MenuAutocompleteListbox>
  </MenuTrigger>
</Flex>
