Example

Previous version:

It is planned in future https://github.com/angular/material2/issues/1429

But now i suspect it is possible. Here is my Plunker Material2 Menu Example that demonstrates such menu

Template might look like this:

<ng-container *ngFor="let item of items">
  <button md-button [mdMenuTriggerFor]="menu" #trigger="mdMenuTrigger" [attr.data-level]="1" (mouseenter)="openMenu(trigger, 1)">
    {{item.text}}
  </button>
  <md-menu class="custom-menu" #menu="mdMenu" [overlapTrigger]="false" (close)="closeMenu()" xPosition="after">
    <ng-container *ngTemplateOutlet="subMenu; context: { $implicit: item.items, level: 2 }"></ng-container>
  </md-menu>
</ng-container>

<ng-template #subMenu let-items let-level="level">
  <ng-container *ngFor="let item of items">
    <ng-container *ngIf="item.items && item.items.length else simpleTmpl">
      <button *ngIf="!item.divider" md-menu-item [disabled]="item.disabled"
              [mdMenuTriggerFor]="menu"
              #trigger="mdMenuTrigger"
              [attr.data-level]="level"
              (mouseenter)="openMenu(trigger, level);" (click)="$event.stopPropagation()">
        <span>{{item.text}}</span>
        <span *ngIf="item.extraText">{{item.extraText}}</span>
        <md-icon *ngIf="item.icon">{{item.icon}}</md-icon>
      </button>
      <md-menu class="sub-menu" #menu="mdMenu" [overlapTrigger]="false" xPosition="before" >
        <ng-container *ngTemplateOutlet="subMenu; context: { $implicit: item.items || [], level: level + 1 }"></ng-container>
      </md-menu>
      <md-divider *ngIf="item.divider" class="mat-divider"></md-divider>
    </ng-container>
    <ng-template #simpleTmpl>
      <button *ngIf="!item.divider" md-menu-item [disabled]="item.disabled" (click)="closeMenu()">
        <span>{{item.text}}</span>
        <span *ngIf="item.extraText">{{item.extraText}}</span>
      </button>
      <md-divider *ngIf="item.divider" class="mat-divider"></md-divider>
    </ng-template>
  </ng-container>
</ng-template>

You need only to declare items definitions:

menuItems = [
  {
    text: 'File',
    items: [
      {
        text: 'Share'
      },
      {
        text: 'New',
        icon: 'arrow_right',
        items: [
          {
            text: 'Document'
          },
          {
            text: 'Form'
          }
        ]
      },
      {
        text: 'Print',
        extraText: 'Ctrl+P'
      }
    ]
  },
  {
    text: 'Edit',
  }
];
