title: jQuery Droppable, get the element dropped
body: <p>A small question hopefully with a simple answer, I am using jQuery draggable and droppable to place items into a dock. Using the below code for the drop.</p>
  
  <pre><code>$("#dock").droppable({
              drop: function(event, ui) {
                  //Do something to the element dropped?!?
              }
          });
  </code></pre>
  
  <p>However I couldn't find a way to get what element was actually dropped, so I can do something do it. Is this possible?</p>
