I've just started with Inline Entity Form and seem to have it working with a custom entity type that has fields. My problem is, none of these fields show in the Inline Entity Form widget, it just shows an empty ID column and Edit / Delete buttons:
I've looked through what little documentation there is, and browsed related issues and questions, but they all seem to be doing things more complex than what I'm trying to do.
Is there any simple way to just choose a field or two to display in the Inline Entity Form widget?
It seems to "just work" for nodes - how can I have it pick up the entity fields in a similar way?
