In webmaps, we can have folders for services added to the map.They have arrows to expand/collapse them. How do we do this in the beta webmap? I just see those folders, but cannot figure out how to access the individual layers.
And please implement the ability for us to create our own folder structure in webmaps! I have hundreds of layers and simply cannot present that many layers to my users with no organization. This is Enterprise GIS, and we need you to help us solve big problems with lots of data. This is a very popular request on ideas.arcgis.com.
