[jQuery] Drop event

Is there a way to acces the drop-event in "ondrop" in a doppable? I
needs the coordinates to show a popup menue:
$(this).attr('isdropabled', '1').Droppable(
{
...,
    ondrop            : function(dropped)
    {
        showPopUpMenu(event, $(dropped).attr('title'), $(this).attr('title'));
    }
});
