Menus display a list of choices on a temporary surface.
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-item
s as well as typeahead functionality.
Additionally, md-menu
interacts with md-menu-item
s 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.

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.

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.
<!-- Note the lack of position: relative parent. -->

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

</script>
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 last child of
- The same
md-menu
is being reused and the contents and anchors are being dynamically changed
<!-- Note the lack of position: relative parent. -->

<md-filled-button id="usage-document-anchor">Open document menu</md-filled-button>

</script>
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"
.

</md-menu>
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.

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 algorithim should calculate relative to the parent of the anchor element (absolute) or relative to the window (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 ancestorWhen 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. |
quick |
quick |
boolean |
false |
Skips the opening and closing animations. |
hasOverflow |
has-overflow |
boolean |
false |
Displays overflow content like a submenu. 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. |
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 focuout 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. |
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. | |
