Menus

Menus display a list of choices on a temporary surface.

Usage

When opened, menus position themselves to an anchor. Thus, either anchor or anchorElement must be supplied to md-menu before opening. Additionally, a shared parent of position:relative should be present around the menu and it's anchor, because the default menu is positioned relative to the anchor element.

Menus also render menu items such as md-menu-item and handle keyboard navigation between md-menu-items as well as typeahead functionality. Additionally, md-menu interacts with md-menu-items to help you determine how a menu was closed. Listen for and inspect the close-menu custom event's details to determine what action and items closed the menu.

Submenus

You can compose <md-menu>s inside of an <md-sub-menu>'s menu slot, but first the has-overflow attribute must be set on the root <md-menu> to disable overflow scrolling and display the nested submenus.

Link to “Popover-positioned menus”

Internally menu uses position: absolute by default. Though there are cases when the anchor and the node cannot share a common ancestor that is position: relative, or sometimes, menu will render below another item due to limitations with position: absolute.

Popover-positioned menus use the native Popover API to render above all other content. This may fix most issues where the default menu positioning (positioning="absolute") is not positioning as expected by rendering into the top layer.

warning
Popover API support was added in Chrome 114 and Safari 17. At the time of writing, Firefox does not support the Popover API (see latest browser compatibility).
For browsers that do not support the Popover API, md-menu will fall back to using fixed-positioned menus.

Open popover menu

<!-- Note the lack of position: relative parent. -->
<div style="margin: 16px;">
  <md-filled-button id="usage-popover-anchor">Open popover menu</md-filled-button>
</div>

<!-- popover menus do not require a common ancestor with the anchor. -->
<md-menu positioning="popover" id="usage-popover" anchor="usage-popover-anchor">
  <md-menu-item>
    <div slot="headline">Apple</div>
  </md-menu-item>
  <md-menu-item>
    <div slot="headline">Banana</div>
  </md-menu-item>
  <md-menu-item>
    <div slot="headline">Cucumber</div>
  </md-menu-item>
</md-menu>

<script type="module">
  const anchorEl = document.body.querySelector('#usage-popover-anchor');
  const menuEl = document.body.querySelector('#usage-popover');

  anchorEl.addEventListener('click', () => { menuEl.open = !menuEl.open; });
</script>

Fixed-positioned menus

Link to “Fixed-positioned menus”

This is the fallback implementation of popover-positioned menus and uses position: fixed rather than the default position: absolute which calculates its position relative to the window rather than the element.

bookmark
Fixed menu positions are positioned relative to the window and not the document. This means that the menu will not scroll with the anchor as the page is scrolled.

Open fixed menu

<!-- Note the lack of position: relative parent. -->
<div style="margin: 16px;">
  <md-filled-button id="usage-fixed-anchor">Open fixed menu</md-filled-button>
</div>

<!-- Fixed menus do not require a common ancestor with the anchor. -->
<md-menu positioning="fixed" id="usage-fixed" anchor="usage-fixed-anchor">
  <md-menu-item>
    <div slot="headline">Apple</div>
  </md-menu-item>
  <md-menu-item>
    <div slot="headline">Banana</div>
  </md-menu-item>
  <md-menu-item>
    <div slot="headline">Cucumber</div>
  </md-menu-item>
</md-menu>

<script type="module">
  const anchorEl = document.body.querySelector('#usage-fixed-anchor');
  const menuEl = document.body.querySelector('#usage-fixed');

  anchorEl.addEventListener('click', () => { menuEl.open = !menuEl.open; });
</script>

Document-positioned menus

Link to “Document-positioned menus”

When set to positioning="document", md-menu will position itself relative to the document as opposed to the element or the window from "absolute" and "fixed" values respectively.

Document level positioning is useful for the following cases:

There are no ancestor elements that produce a relative positioning context.
- position: relative
- position: absolute
- position: fixed
- transform: translate(x, y)
- etc.
The menu is hoisted to the top of the DOM
- The last child of <body>
- Top layer
The same md-menu is being reused and the contents and anchors are being dynamically changed

Open document menu

<!-- Note the lack of position: relative parent. -->
<div style="margin: 16px;">
  <md-filled-button id="usage-document-anchor">Open document menu</md-filled-button>
</div>

<!-- document menus do not require a common ancestor with the anchor. -->
<md-menu positioning="document" id="usage-document" anchor="usage-document-anchor">
  <md-menu-item>
    <div slot="headline">Apple</div>
  </md-menu-item>
  <md-menu-item>
    <div slot="headline">Banana</div>
  </md-menu-item>
  <md-menu-item>
    <div slot="headline">Cucumber</div>
  </md-menu-item>
</md-menu>

<script type="module">
  const anchorEl = document.body.querySelector('#usage-document-anchor');
  const menuEl = document.body.querySelector('#usage-document');

  anchorEl.addEventListener('click', () => { menuEl.open = !menuEl.open; });
</script>

Accessibility

Link to “Accessibility”

By default Menu is set up to function as a role="menu" with children as role="menuitem". A common use case for this is the menu button example, where you would need to add keyboard interactions to the button to open the menu (see W3C example).

Menu can also be adapted for other use cases.

The role of the md-list inside the menu can be set with the type attribute. The role of each individual md-menu-item can also be set with the type attribute. Anything else slotted into the menu that is not a list item in most cases should be set to role="none", and md-divider should have role="separator" and tabindex="-1".

    id="textfield"
    type="combobox"
    aria-controls="menu"
    aria-autocomplete="list"
    aria-expanded="true"
    aria-activedescendant="1"
    value="Ala">
</md-filled-text-field>
<md-menu
    id="menu"
    anchor="textfield"
    role="listbox"
    aria-label="states"

  <md-menu-item type="option" id="0">
    <div slot="headline">Alabama</div>
  </md-menu-item>
  <md-divider role="separator" tabindex="-1"></md-divider>
  <md-menu-item type="option" id="1" selected aria-selected="true">
    <div slot="headline">Alabama</div>
  </md-menu-item>
</md-menu>

Theming

Link to “Theming”

Menus support Material theming and can be customized in terms of color. Additionally, md-menu composes md-list, and each menu item extends md-list-item (see theming documentation), so most the tokens for those components can also be used for Menu.

MdMenu `<md-menu>`

Link to “MdMenu <md-menu>”

Properties

Link to “Properties”

Property	Attribute	Type	Default	Description
`anchor`	`anchor`	`string`	`''`	The ID of the element in the same root node in which the menu should align to. Overrides setting `anchorElement = elementReference`. NOTE: anchor or anchorElement must either be an HTMLElement or resolve to an HTMLElement in order for menu to open.
`positioning`	`positioning`	`string`	`'absolute'`	Whether the positioning algorithm should calculate relative to the parent of the anchor element (`absolute`), relative to the window (`fixed`), or relative to the document (`document`). `popover` will use the popover API to render the menu in the top-layer. If your browser does not support the popover API, it will fall back to `fixed`. Examples for `position = 'fixed'`: - If there is no `position:relative` in the given parent tree and the surface is `position:absolute` - If the surface is `position:fixed` - If the surface is in the "top layer" - The anchor and the surface do not share a common `position:relative` ancestor When using `positioning=fixed`, in most cases, the menu should position itself above most other `position:absolute` or `position:fixed` elements when placed inside of them. e.g. using a menu inside of an `md-dialog`. NOTE: Fixed menus will not scroll with the page and will be fixed to the window instead. Examples for `position = 'document'`: - There is no parent that creates a relative positioning context e.g. `position: relative`, `position: absolute`, `transform: translate(x, y)`, etc. - You put the effort into hoisting the menu to the top of the DOM like the end of the `<body>` to render over everything or in a top-layer. - You are reusing a single `md-menu` element that dynamically renders content. Examples for `position = 'popover'`: - Your browser supports `popover`. - Most cases. Once popover is in browsers, this will become the default.
`quick`	`quick`	`boolean`	`false`	Skips the opening and closing animations.
`hasOverflow`	`has-overflow`	`boolean`	`false`	Displays overflow content like a submenu. Not required in most cases when using `positioning="popover"`. NOTE: This may cause adverse effects if you set `md-menu {max-height:...}` and have items overflowing items in the "y" direction.
`open`	`open`	`boolean`	`false`	Opens the menu and makes it visible. Alternative to the `.show()` and `.close()` methods
`xOffset`	`x-offset`	`number`	`0`	Offsets the menu's inline alignment from the anchor by the given number in pixels. This value is direction aware and will follow the LTR / RTL direction. e.g. LTR: positive -> right, negative -> left RTL: positive -> left, negative -> right
`yOffset`	`y-offset`	`number`	`0`	Offsets the menu's block alignment from the anchor by the given number in pixels. e.g. positive -> down, negative -> up
`typeaheadDelay`	`typeahead-delay`	`number`	`200`	The max time between the keystrokes of the typeahead menu behavior before it clears the typeahead buffer.
`anchorCorner`	`anchor-corner`	`string`	`Corner.END_START`	The corner of the anchor which to align the menu in the standard logical property style of-e.g. `'end-start'`. NOTE: This value may not be respected by the menu positioning algorithm if the menu would render outisde the viewport.
`menuCorner`	`menu-corner`	`string`	`Corner.START_START`	The corner of the menu which to align the anchor in the standard logical property style of-e.g. `'start-start'`. NOTE: This value may not be respected by the menu positioning algorithm if the menu would render outisde the viewport.
`noHorizontalFlip`	`no-horizontal-flip`	`boolean`	`false`	Disable the `flip` behavior that usually happens on the horizontal axis when the surface would render outside the viewport.
`noVerticalFlip`	`no-vertical-flip`	`boolean`	`false`	Disable the `flip` behavior that usually happens on the vertical axis when the surface would render outside the viewport.
`stayOpenOnOutsideClick`	`stay-open-on-outside-click`	`boolean`	`false`	Keeps the user clicks outside the menu. NOTE: clicking outside may still cause focusout to close the menu so see `stayOpenOnFocusout`.
`stayOpenOnFocusout`	`stay-open-on-focusout`	`boolean`	`false`	Keeps the menu open when focus leaves the menu's composed subtree. NOTE: Focusout behavior will stop propagation of the focusout event. Set this property to true to opt-out of menu's focusout handling altogether.
`skipRestoreFocus`	`skip-restore-focus`	`boolean`	`false`	After closing, does not restore focus to the last focused element before the menu was opened.
`defaultFocus`	`default-focus`	`string`	`FocusState.FIRST_ITEM`	The element that should be focused by default once opened. NOTE: When setting default focus to 'LIST_ROOT', remember to change `tabindex` to `0` and change md-menu's display to something other than `display: contents` when necessary.
`noNavigationWrap`	`no-navigation-wrap`	`boolean`	`false`	Turns off navigation wrapping. By default, navigating past the end of the menu items will wrap focus back to the beginning and vice versa. Use this for ARIA patterns that do not wrap focus, like combobox.
`isSubmenu`		`boolean`	`false`	Whether or not the current menu is a submenu and should not handle specific navigation keys.
`typeaheadController`		`TypeaheadController`	`function { ... }`	Handles typeahead navigation through the menu.
`anchorElement`		`HTMLElement & Partial<SurfacePositionTarget>`	`undefined`
`items`		`MenuItem[]`	`undefined`
