title: What is an example of a material design angular2/4 menu with nested dropdown options like angular1?
body: <p>I really want to incorporate angular2 material, noticed the following menu example:</p>
  
  <pre><code>https://material.angularjs.org/1.1.4/demo/menuBar
  </code></pre>
  
  <p>This is a beauty: <a href="http://codepen.io/anon/pen/zrdQwP" rel="nofollow noreferrer">http://codepen.io/anon/pen/zrdQwP</a></p>
  
  <p>I like how you can have nested menus, but for the Angular 2/4 demo, all you see is this:</p>
  
  <pre><code>https://material.angular.io/components/component/menu
  </code></pre>
  
  <p>There is no example with nested menus! Is this possible with Angular2 + Material? If so, can someone demonstrate how to use this? Or is this just not possible? Seems fishy if Angular 2/4 can't support this while Angular 1.x can...</p>
