Menu

Overview for menu

<mat-menu> is a floating panel containing list of options.

Basic menu

By itself, the <mat-menu> element does not render anything. The menu is attached to and opened via application of the matMenuTriggerFor directive:

The menu exposes an API to open/close programmatically. Please note that in this case, an matMenuTriggerFor directive is still necessary to attach the menu to a trigger element in the DOM.

class MyComponent {
  @ViewChild(MatMenuTrigger) trigger: MatMenuTrigger;

  someMethod() {
    this.trigger.openMenu();
  }
}

Menus support displaying mat-icon elements before the menu item text.

By default, the menu will display below (y-axis), after (x-axis), without overlapping its trigger. The position can be changed using the xPosition (before | after) and yPosition (above | below) attributes. The menu can be forced to overlap the trigger using the overlapTrigger attribute.

Material supports the ability for an mat-menu-item to open a sub-menu. To do so, you have to define your root menu and sub-menus, in addition to setting the [matMenuTriggerFor] on the mat-menu-item that should trigger the sub-menu:

By default, the menu content will be initialized even when the panel is closed. To defer initialization until the menu is open, the content can be provided as an ng-template with the matMenuContent attribute:

<mat-menu #appMenu="matMenu">
  <ng-template matMenuContent>
    <button mat-menu-item>Settings</button>
    <button mat-menu-item>Help</button>
  </ng-template>
</mat-menu>

<button mat-icon-button [matMenuTriggerFor]="appMenu">
  <mat-icon>more_vert</mat-icon>
</button>

When using lazy rendering, additional context data can be passed to the menu panel via the matMenuTriggerData input. This allows for a single menu instance to be rendered with a different set of data, depending on the trigger that opened it:

<mat-menu #appMenu="matMenu">
  <ng-template matMenuContent let-name="name">
    <button mat-menu-item>Settings</button>
    <button mat-menu-item>Log off {{name}}</button>
  </ng-template>
</mat-menu>

<button mat-icon-button [matMenuTriggerFor]="appMenu" [matMenuTriggerData]="{name: 'Sally'}">
  <mat-icon>more_vert</mat-icon>
</button>

<button mat-icon-button [matMenuTriggerFor]="appMenu" [matMenuTriggerData]="{name: 'Bob'}">
  <mat-icon>more_vert</mat-icon>
</button>
  • DOWN_ARROW: Focuses the next menu item
  • UP_ARROW: Focuses previous menu item
  • RIGHT_ARROW: Opens the menu item's sub-menu
  • LEFT_ARROW: Closes the current menu, if it is a sub-menu
  • ENTER: Activates the focused menu item
  • ESCAPE: Closes the menu

Menu triggers or menu items without text or labels should be given a meaningful label via aria-label or aria-labelledby.
