You can override

        onDragEnter: function(node, sourceNode) {
          /** sourceNode may be null for non-fancytree droppables.
           *  Return false to disallow dropping on node. In this case
           *  onDragOver and onDragLeave are not called.
           *  Return 'over', 'before, or 'after' to force a hitMode.
           *  Return ['before', 'after'] to restrict available hitModes.
           *  Any other return value will calc the hitMode from the cursor position.
           */
          // Prevent dropping a parent below another parent (only sort
          // nodes under the same parent)
/*           if(node.parent !== sourceNode.parent){
            return false;
          }
          // Don't allow dropping *over* a node (would create a child)
          return ["before", "after"];
*/
           return true;
        },
