The following code only makes one copy (clone) of the original element. After the clone is dragged (and dropped), I can no longer make another clone of the original element.
I want the original element to be cloned every time it is dragged. Can someone steer me in the right direction?

Code:
$(function(){
		$(".droptrue").draggable({
                			snap: '#dropTargetframe',
                			connectToSortable: '#dropTargetframe',
                			helper: 'clone',
                                   	cursor: 'move',
                			revert: false
			});   

		$("#dropTargetframe").sortable({
                			revert: false
			});              

		$("#dropTargetframe").droppable({
                			revert: 200,
                			receive: cloneMe 
 			});
 
		function cloneMe(event, ui) {
    			ui.item.clone().appendTo('#dropTargetframe');
			}
	});
