I am using the awesome Panels module to override the default taxonomy display. I am using the Related Terms content pane (built-in to Panels) to show children of the current term.
My vocabulary looks like this:
What I would like to do is show the child terms (related terms pane) only for countries, not states or cities. In other words, I would like to show the related terms pane if and only if the term has no parents except the root parent.
However, the only Visibility Rule that seems to apply is Term has Parent(s), which requires a user-created term (not the root term) to be selected. I could select all of the terms and then check Reverse, but I have hundreds of locations and more are being added all the time, making this unfeasible. Is there some other way?
