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:
- <Menu>: The main wrapper that provides nested components with all the context and state.
- <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- forwardReffor functional components.
- <Menu.List>: The wrapper for the menu items. Must be a direct child of- <Menu>.
- <Menu.Item>The trigger that handles menu selection. Must be a direct child of- <Menu.List>.
- <Menu.Divider>A visual separator for menu items.
- <Menu.SectionTitle>A title that you can use in the menu list.
- <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.
- <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.
- <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>.
- <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
import React from 'react';import { Menu, IconButton } from '@contentful/f36-components';import { MenuIcon } from '@contentful/f36-icons';export default function MenuOpenByDefault() {return (<Menu defaultIsOpen><Menu.Trigger><IconButtonvariant="secondary"icon={<MenuIcon />}aria-label="toggle menu"/></Menu.Trigger><Menu.List><Menu.Item>Create an entry</Menu.Item><Menu.Item>Remove an entry</Menu.Item><Menu.Item>Embed existing entry</Menu.Item></Menu.List></Menu>);}
With sticky header and footer
With React Router links
import React from 'react';import { Router, Link } from 'react-router-dom';import { Menu, IconButton } from '@contentful/f36-components';import { MenuIcon } from '@contentful/f36-icons';export default function MenuWithReactRouterLinks() {return (<Router><Menu><Menu.Trigger><IconButtonvariant="secondary"icon={<MenuIcon />}aria-label="toggle menu"/></Menu.Trigger><Menu.List><Link to="/" component={Menu.Item} as="a">Home</Link><Link to="/about" component={Menu.Item} as="a">About</Link><Link to="/other" component={Menu.Item} as="a">Other</Link></Menu.List></Menu></Router>);}
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.
Menu
- Namechildren(required)ReactNode
- NamecloseOnBlurDescriptionIf true, the menu will close when you blur out it by clicking outside Note: This prop will be propagated to all submenus, unless you will override it with props on submenu itself falsetrue
- NamecloseOnEscDescriptionIf true, the menu will close when you hit the Esc key Note: This prop will be propagated to all submenus, unless you will override it with props on submenu itself falsetrue
- NamecloseOnSelectDescriptionIf `true`, the Menu will close when a menu item is clicked Note: This prop will be propagated to all submenus, unless you will override it with props on submenu itself falsetrue
- NamedefaultIsOpenDescriptionIf `true`, the Menu will be initially opened. falsetrue
- NameisAutoalignmentEnabledDescriptionBoolean to control if popover is allowed to change its placement automatically based on available space in the viewport. For example: If you set placement prop to bottom, but there isn't enough space to position the popover in that direction, it will change the popper placement to top. As soon as enough space is detected, the placement will be reverted to the defined one. If you want the popover to strictly follow the placement prop you should set this prop to false. falsetrue
- NameisFullWidthDescriptionBoolean to determine if the Popover should be the same width as the trigger element falsetrue
- NameisOpenDescriptionIf `true`, the Menu will be opened in controlled mode. By default the Menu is uncontrolled falsetrue
- NameoffsetDescriptionThe `X-axis` and `Y-axis` offset to position popper element from its trigger element. `[X, Y]` [number, number]
- NameonCloseDescriptionCallback fired when the Menu closes () => void
- NameonOpenDescriptionCallback fired when the Menu opens () => void
- NameplacementDescriptionDetermines the preferred position of the Popover. This position is not guaranteed, as the Popover might be moved to fit the viewport "auto""auto-start""auto-end""top""bottom""right""left""top-start""top-end""bottom-start""bottom-end""right-start""right-end""left-start""left-end"
- NameusePortalDescriptionBoolean to control whether or not to render the Popover in a React Portal. Rendering content inside a Portal allows the Popover to escape the bounds of its parent while still being positioned correctly. Using a Portal is necessary if an ancestor of the Popover hides overflow. falsetrue
Menu.Item
