<pre><code>drop: function( event, ui)
        {
            draggableDocumentOffset = ui.helper.offset(),
            droppableDocumentOffset = $(this).offset(),  
            left = draggableDocumentOffset.left - droppableDocumentOffset.left,
            top = draggableDocumentOffset.top - droppableDocumentOffset.top; 
        }
</code></pre>

<p>I am using a div as a droppable area. I want to get the position of the dropped element relative to the div in which it is being dropped.</p>
