I am trying to disable the drag/drop within the treeview (as in the user wont be able to move any items anywhere inside the treeview). However I am not coming up with a solution for this issue.

I still want the user to be able to drag/drop an item that's inside the treeview over to my listview box as well as drag/drop it back to the treeview box.

So is it possible to disable the drag/drop feature inside the treeview when keeping the drag/drop from there to my listbox?

Hello David,

I would suggest you in the drop event handler of the TreeView to check the target destination and prevent the default behavior if needed. Below is an example:

function onDrop(e){          
       
        if($(e.destinationNode).attr('role') == "treeitem"){          
          
          e.preventDefault()
          
        } 
         .....
}

Here is a Dojo example where this is demonstrated.

Let me know in case you have additional questions on the matter..
