title: JavaFX 2 - Autoscroll to last item in exceeded toolbar
body: <p>I am creating File Manager like Miller column app for windows in JavaFX for learning purpose.
  Check the screenshot below:

  <p>As you can see, when toolbar exceeds, there comes a double arrow button for more items to select from popup.</p>
  
  <p>I already did auto scroll for miller column, which works as expected.</p>
  
  <pre><code>scrollPane.hvalueProperty().bind(hBox.widthProperty());
  </code></pre>
  
  <p><b>I would like to auto scroll toolbar to last item and show double arrow on left side.</b><br>
  I am adding adding clickable buttons in toolbar for traversing like manual BreadCumBar.<br><br>
  <i>Tried ControlsFX BreadCumBar, it doesn't even show arrows or popup when exceeds, Bug here : <a href="https://bitbucket.org/controlsfx/controlsfx/issues/810/no-double-arrow-popup-like-when" rel="nofollow noreferrer">https://bitbucket.org/controlsfx/controlsfx/issues/810/no-double-arrow-popup-like-when</a>.</i><br><br>
  <b>If its not possible to do so with toolbar, I would like to know how to customize toolbar popup only via css. Or any other way that improve usability easiness. </b><br>
  Also I would love to know suggestions for whole app from expert designers.</p>
  
  <p>Thanks.</p>
