  Hello,

  thank you for the widget!
  
  Two questions concerning it:

  1. is it possible to d&d in “copy” instead of “move” mode?
  2. is it possible to d&d to a target different from TreeView?
     
     (ListBox or Grid)

  Regards
  
  Richard

  Hello Richard,
  
  We apologize for the delayed response.
  
  There is no direct way for copy node on drag and drop instead of move. However, you can handle dragStart and drop event of tree view and update source accordingly.
  
  For your reference, please see the attached sample that implements the same.

  Regarding Drag and drop to different target(except TreeView control ), we are investigating and let you know as soon as we get any update on this.

  Thanks,

  Hi,
  
  The control uses the standard HTML5 drag/drop API, so you can craete custom drop targets for nodes by handling a few HTML events. For example:

  For details about the standard HTML5 drag/drop API, see here:
