Description

  • Vaadin version :8.1.1
  • Description of the bug: There seems to be no API for node drag and drop for Tree Nodes. Applying DragSourceExtension and DropTargetExtension doesnt seem to make any effect.
    I see Tree uses TreeGrid internally. And for TreeGrid, there seem to a special extension TreeGridDragSource . But this can not be applied to Tree.

Is DnD in tree nodes still supported. Or will it come in coming versions?

Research direction

Review Tree, TreeGrid, TreeGridDragSource, DragSourceExtension, and DropTargetExtension to determine how node drag-and-drop is currently handled. Confirm whether Tree node drag-and-drop is supported in Vaadin 8.1.1; done means documenting the supported path or clearly defining the missing API behavior.
