I have been investigating the capability provided by the containment function in UN. This makes a very clean looking map in pro. The first 2 images below are showing ducts, duct banks and electric lines with containment - display content hidden then shown.
This third image is the same dataset in a portal map. As you can see there is no containment and all the objects are visible.
Is there any configuration we need to set to allow the portal users to utilise containment? Or are the users stuck with the objects always shown?
