Rails - Oct 2006 - Problem with Sortable.create and the "only" option

Hi,

   I have the following issue :
I have 2 classes of elements which can be dragged/dropped - lineitem and 
mandatorylineitem.

I have 2 goups - optional and mandatory. I do not want the mandatory 
items to be dragged and dropped into the optional group. I create the 
Sortables in the following manner :

Sortable.create(''group_1'',{tag:''div'',dropOnEmpty:
true, containment:
[''group_2''],only:[''mandatorylineitem'',''lineitem'']});

Sortable.create(''group_2'',{tag:''div'',dropOnEmpty:
true, containment:
[''group_1''],only:''lineitem''});

But, to no avail. Could someone help me regarding this. Probably I 
havent understood the meaning of the "only" option for
Sortable.create.

Solved. Used the following :

		var draggedElement;
	
Sortable.create(''group_1'',{tag:''div'',dropOnEmpty:
true, containment:
[''group_2''],only:''lineitem'',onUpdate:
function(element) {
			var htmlElement = element.innerHTML
			if(htmlElement.indexOf(''(Mandatory Attachment)'') != -1){
				$(''group_2'').appendChild(draggedElement);
			}}, onChange: function(ele){
				draggedElement = ele;
			}});
