What I am trying to accomplish:
I want to have a point feature class named "Stations" with a child point feature class named "Valves". In field maps when you click a Station, the popup shows the associated Valves. Then selecting a Valve in the popup brings up that item, where you can then edit the Status field to On or Off.
How I've been trying to do it:
In Pro I have created two point feature classes. They both have a text field named "StationID". I've created a relationship class. (simple, one-to-many, unattributed, Station StationID as primary key, Valve StationID as foreign key) Publish as a web layer. In Online, go into the parent layer settings. turn on editing capabilities, allow to add, delete, and update. Create a map to test it out. Set up the forms in Field Maps Designer. Test it out in field maps (reloading the map every time)
Where I seem to be stuck:
In Field Maps, there is no + to add features. And when any feature is selected there is no option to edit.
