title: Retrieving X & Y position of jQuery element
body: <p>I need to retrieve the X &amp; Y position of an element once its dropped, how can I implement this ? </p>
  
  <p>I think I need to use the droppable callback : </p>
  
  <pre><code>$(".portletPlaceHolder").droppable({
      drop: function( event, ui ) {
          //...
      }
  });
  </code></pre>
