Suppose, if we have a series of girds and want to know from which grid dragging is started, we can implement the following code, but I think there should be another option dealing this situation; though we have only two options ‘out’ and ‘over’, and can use them.

1.   var droppableStart = '';
2.     $("#draggable").draggable({
3.         start: function(){
4.           droppableStart = '';
5.         }
6.       });
7.     $(".gridArea").droppable({
8.       tolerance: 'intersect',
9.       over: function() {
10.         if(droppableStart == ''){
11.           droppableStart = $(this).attr('id');
12.         }
13.       },
14.     drop: function() {
15.            alert(droppableStart);
16.        }
17.     });
