My issue is something similar to this one - Best UI pattern for letting a user assign items to groups
I am looking for a good UI design for mapping items between 2 groups (only one-to-one mapping). These items can be under a parent or by itself. I thought of drag-and-drop/ having checkboxes (or switch like) to turn on for any one group.
Items Group 1 Group 2
Item A1 checkbox checkbox
Item B checkbox checkbox
