title: Removing sub header on specific pages(ionic)
body: <p>I am trying to hide a sub header with a button bar in it on specific pages, at the moment it is showing on all pages. I have a <code>nav</code> bar above that will remain on every page. Here is the code for the headers. </p>
  
  <pre><code>&lt;ion-nav-bar class="bar-dark" align-title="center"&gt;
  
      &lt;ion-nav-back-button&gt;&lt;/ion-nav-back-button&gt;
  
      &lt;ion-nav-buttons side="left"&gt;
          &lt;button class="button button-icon button-clear ion-ios-gear"&gt;&lt;/button&gt;
      &lt;/ion-nav-buttons&gt;
  
      &lt;ion-nav-buttons side="right"&gt;
          &lt;button class="button button-icon button-clear ion-ios-cart-outline" &gt;&lt;/button&gt;
      &lt;/ion-nav-buttons&gt;
  &lt;/ion-nav-bar&gt;
  
  
  
  
  
  &lt;ion-header-bar align-title="center" class="bar-subheader bar-light"  &gt;
      &lt;div class="button-bar"&gt;
          &lt;a class="button button-outline button-dark"&gt;Sort&lt;/a&gt;
          &lt;a class="button button-outline button-dark"&gt;Categories&lt;/a&gt;
          &lt;a class="button button-outline button-dark"&gt;Filter&lt;/a&gt;
      &lt;/div&gt;
  
  &lt;/ion-header-bar&gt;
  </code></pre>
  
  <p>Thank you</p>
