how to drag from a scrollable div to a droppable and then drag again?
I have a scrollable list on the left of the page (overflow:auto) and several droppables on the right of the page. I found a workaround to allow an element to be dragged from the list to a container using a clone here but when the element is dropped, it gets position:absolute and a top and right position added to an inline style along with the z-index which was originally there. All other classes attached are in the copy, just that after the drag and drop, that element cannot be dragged again ?
Is there a way to do this or to remove the inline style added by the cloning process ?
Simplified code showing the issue is shown below - you should be able to just cut and paste to a page and drop in your webroot to test it. Thanks in advance.

In your draggable stop method, I took the cloned element and made it draggable.
stop: function(event, ui) {
if (dropped==true) {
$(this).remove();
} else {
$(this).removeClass("hide");
}
$('#'+$(this).attr('id')).draggable({revert: 'invalid'});
}
When the dragging element is cloned, it preserves the "ui-draggable" class, but that's not enough to make it draggable. It must be rebound.
