Thank you Long, this would be a really nice feature to have!
Okay, what about the other way around?
Is it possible to add the relationship as a field in a normal metabox somehow?
Any updates on this?
It's very annoying to have to keep one item, and delete all it's content.
I want to be able to remove all items in the list, so that only the button is there. If i click it, the first item should be created.
I'm looking for exactly this! Would you mind sharing it?
