    Hello,

    i have a strange behavior on assigning a item a second time.

    Starting situation: I have a jqxTree with several items like this:

    – apple
    – oracle
    – microsoft

    I drag and drop one item in another like this:

    – apple
    |- microsoft
    – oracle

    That works fine. Now I want that the item (microsoft) would be copied and the copy should be assigned to apple and the original remains in its original position.

    I have implemented the following (simple modified from the sample code ‘drag and drop’):

    $('#treeA').jqxTree({ allowDrag: true, allowDrop: true, height: '300px', width: '220px', 
            dragEnd: function (item, dropItem, args, dropPosition, tree) {
            	$('#treeA').jqxTree('addTo', dropItem, item, true);
            	return false;
            }
        });

    Until then it works but if i drag the microsoft item a second time, the value ‘item’ is null.

    Any suggestions? Thanks in advance.

    Hello Emanuel,

    Unfortunately, such implementation is not supported by jqxTree because calling addTo in the dragEnd callback interferes with the proper rendering of the widget.
