    Hello,

    Well actually what happens is that on the client a NodeDrop event is fired and you can customize whether a node becomes a child or a sibling of the destionation node there. For example, please take a look at the following sample

    There you will see the following code that actually makes the node a child of the destination node

            function UltraWebTree1_Drop(oTree, oNode, oDataTransfer, oEvent){
                var sourceNode = oDataTransfer.sourceObject;
                if(!oNode.isChildOf(sourceNode))
                {
                    oNode.addChild(oDataTransfer.dataTransfer.getData("Text"));
                    oNode.setExpanded(true);                
                    if(sourceNode)
                        sourceNode.remove();
                }
                return false;
            }

    So I believe starting from this sample and tweaking the Drop even will lead you to the right path (e.g. not use addChild for the destionation node, but rather for its parent)
