Use case description (required)

I got a kanban board that has "notes" in it, you can think of them basically like tasks but some are actually projects which are basically tasks that have subtasks. Is there a way when I'm draggin from column to column to check if I'm also dragging on top of another "note" and then trigger a different function?
