title: Ionic2 close fab menu when button pressed
body: <p>How can I close the open FAB menu when a button in the menu was pressed?</p>
  
  <p>Here's my button.</p>
  
  <pre><code>&lt;ion-fab bottom center &gt;
  &lt;button ion-fab&gt;&lt;b&gt;Hello&lt;/b&gt;&lt;/button&gt;
  &lt;ion-fab-list side="top"&gt;
  &lt;button ion-fab (click)="refresh()"&gt;&lt;ion-icon name="refresh"&gt;&lt;/ion-icon&gt;&lt;/button&gt;
  </code></pre>
  
  <p>What would I have to add to <code>refresh</code> to make the whole FAB close?
  Can I somehow reference the html object from within the code? Similar to the way iOS handles it's outlets?</p>
