title: ExtJS 3 -- Always Show menu icon in GridPanel Column Header?
body: <p>I have a requirement to always show the menu icon in a a GridPanel's column header.  See attached image.  I've tracked down the css class and see the <code>&lt;td /&gt;</code> tag is assigned the <code>x-grid3-hd-btn</code> on hover.  The <code>x-grid3-hd-btn</code> class uses a background image, <code>grid3-hd-btn.gif</code> to display the drop-down arrow I want, but I'm not css savvy enough to figure out how to always show it.</p>

  <p>There doesn't seem to be a hook in the GridPanel class api's to always display this, wish there was.  Also, note that I only want the arrow icon to show, I don't want the column header to change color, etc.</p>
  
  <p>Does anyone have any guidance on this?</p>
  
  <p>Thanks!</p>
