Context
- Difficult to add a child location in the right place.
- Add child term button on detail page.
- Added experimental views add button.
- Only Enhanced Taxonomy Manager has a way to add a child term, but not to top level terms (bug).
- Improve parent selection widget.
- Looks like a core issue is preventing selection of any hierarchy ref widgets.
Discovery
Investigate taxonomy hierarchy modules
Analysis
Taxonomy Entity allows setting a vocabulary's hierarchy settings.
Otherwise, it will determine the hierarchy type dynamically.
Only 3 users, and several issues. But has potential for what I'm looking for.
I can set the taxonomy to be a single parent hierarchy, and it will have a select widget for a single parent.
