Menu is a component that offers a list of choices to the user, such as a set of actions or links. Menu uses Popover component as a base.

Import

import { Menu } from '@contentful/f36-components';

Examples

You can use following components to build a menu:

  1. <Menu>: The main wrapper that provides nested components with all the context and state.
  2. <Menu.Trigger> The wrapper for the menu list trigger. Must be a direct child of <Menu>.
    NOTE: 🚨 Ensure that the component that you pass accepts ref. Consider using forwardRef for functional components.
  3. <Menu.List>: The wrapper for the menu items. Must be a direct child of <Menu>.
  4. <Menu.Item> The trigger that handles menu selection. Must be a direct child of <Menu.List>.
  5. <Menu.Divider> A visual separator for menu items.
  6. <Menu.SectionTitle> A title that you can use in the menu list.
  7. <Menu.ListHeader> The wrapper for one menu item that will be sticked to the top of the menu list. <Menu.Item> must be provided as a child.
  8. <Menu.ListFooter> The wrapper for one menu item that will be sticked to the bottom of the menu list. <Menu.Item> must be provided as a child.
  9. <Menu.Submenu> The wrapper for for submenu components. Structure of the children remains the same like in <Menu>, except you should use <Menu.SubmenuTrigger> instead of <Menu.Trigger>.
  10. <Menu.SubmenuTrigger> The wrapper for the submenu list trigger. Must be a direct child of <Menu.Submenu>.

Basic usage


With simple Button as a trigger


With Menu.SectionTitle and Menu.Divider


Controlled Menu

By default the Menu component is uncontrolled. So when user clicks on the trigger, the menu opens/closes. But you can control it by passing isOpen prop and onClose, onOpen callbacks.


Controlled Menu with custom trigger onClick callback

In most cases, you will use the controlled approach. But if you have to provide your own toggle menu logic on the trigger component, you can do this by providing onClick callback on trigger component and omitting onOpen callback on the Menu component.


With Menu list maximum height


With disabled items


With menu open by default


With sticky header and footer


With React Router links


With predefined focused menu item


With submenu

By default props like closeOnSelect, closeOnBlur, closeOnEsc that you pass to Menu will be shared to all submenus but you can redefine them on any submenu by passing those props directly to that Submenu.


Props (API reference)

Menu

Menu.Item

Menu.List

Content guidelines

  • Use an interactive element such as button for Menu.Trigger

Accessibility

  • When the menu is opened, focus is moved to the first menu item. If you set autoFocusto false, it will not move the focus.
  • When the menu is closed, focus returned back to the trigger element.
  • You can use arrow keys (ArrowUp and ArrowDown) to navigate through menu items.
  • When the menu is open, click on Esc key will close the popover. If you set closeOnEsc to false, it will not close.
  • When the menu is open, click outside menu or blurring out will close the menu. If you set closeOnBlur to false, it will not close.
  • All the necessary a11y attributes for Menu.List, Menu.Trigger and Menu.Item are provided.
