title: Ionic tab menu not showing or can't slide in from right
body: <p>I want two navbar buttons, one for search and one for sliding the menu
  Using the below code,</p>
  
  <pre><code>&lt;ion-header&gt;
  
    &lt;ion-navbar&gt;
      &lt;ion-title&gt;{{ 'START_TAB' | translate }}&lt;/ion-title&gt;
  
      &lt;ion-buttons right&gt;
        &lt;button ion-button icon-only (click)="search()"&gt;
          &lt;ion-icon name="search"&gt;&lt;/ion-icon&gt;
        &lt;/button&gt;
        &lt;button ion-button menuToggle="right"&gt;
          &lt;ion-icon name="menu"&gt;&lt;/ion-icon&gt;
        &lt;/button&gt;
      &lt;/ion-buttons&gt;
    &lt;/ion-navbar&gt;
  
  &lt;/ion-header&gt;
  </code></pre>
  
  <p>The menu button is missing altogether.

  <p>When I remove <code>menuToggle="right"</code> parameter, I get the below result:</p>

  and the toggle is from the left side as expected. </p>
  
  <p>How do I make it toggle from the right and the icons be horizontally placed?</p>
