Hi,
What about functionality for adding both a parent and a child term (and even a grandchild term)? Perhaps the second single line text field could look for 2nd level terms?
I’m thinking through a problem where the user will submit terms to a location taxonomy – state, city, place. The idea being that at each place there are a few projects (custom posts).
In theory, couldn’t you have a set of text fields, with the first being the parent, the second the child, and the third the grandchild?
