We are attempting a build out of our telecommunications map using ArcGIS Online based on the concepts of the "Communications Data Management" solution, but frankly, it's too much.
We really like how it has hosted feature layers with sublayers for each subsystem, but are 1) unable to replicate it and 2) unable to easily edit what it creates.
Specifically, how do you create a feature layer with sublayers and add/remove sublayers from that feature layer? I see how to create Grouped layers, but not how to do sublayers using the web GUI or even using ArcGIS Pro.
I have seen how to do it with json, but somehow we corrupted our first attempt and now have layers that don't show up even though they are in the json. 😮
