title: How to rotate triangle collapse icon in Ext Js panel?
body: <p>Is there a way to rotate the collapse icon in a panel ( <a href="http://i.imgur.com/2ZvKd.png" rel="nofollow">http://i.imgur.com/2ZvKd.png</a> )? Since the direction is a bit misleading as the panel collapses in a direction opposite to that what the icon indicates.</p>
  
  <pre><code>   defaults: {
              collapsible: true,
              animFloat: true,
              autoHide: true,
              cmargins: '5 5 5 5'
          },
          items:
          [{
              xtype: 'createreportview',
              bodyStyle:{ padding: '10px'},
              minHeight:280,
              flex: 0.40
           },
           {
               xtype: 'splitter',
               collapseTarget:'prev'
           },
           {
               xtype: 'resultsview',
               flex: 0.60
          }]
  }
  </code></pre>
  
  <p>There are 2 panels, the collapse icon on the 2nd panel (resultsview) is the one shown in the image posted above and is the one im trying to fix.</p>
