There was a problem hiding this comment.
This is complete guess work. I don't know what is happening behind the scenes, but these are the assumptions that led to a working solution. There was definitely some funny duplication happening, though I cannot say for certain that it was due to the index changing, just that it happened when the index changed
|
I just found out that the duplication glitch shows up again when multi-select is enabled. Putting this back into WIP |

I should have some more time to work on this in a couple weeks (after finals). The key findings are the need to add the
dndoption to thepluginslist and that the move event can be triggered on viamove_node.jstree.The current logic for updating children nodes and all that (327-353) fails to update other copies of the ipytree widget (due to the silent option) so that needs to be reworked.
Also, there should probably be an option for enabling and disabling
dnd. I'm not sure how to do that yet.
