Programmatic grab and ungrab functionality

[killbotXD]

Hey, I was trying to create a drag and drop functionality between 2 canvasses.

I am using the compound-drag-and-drop extension to create a compounded graph of sparse nodes that when dragged out of the compound, trigger the cdndout event in turn programnmatically adding the node to the other canvas, but the UX is pretty bad as the node from canvas 1 remains active and grabbed. I wanted to know if there is a way to ungrab the node from canvas1 and grab the new added node of canvas2(whose position is determined by the pointer location) programmatically.

Any help is Appreciated :)
