Does anyone have a custom WAB widget that views related tables (with multiple levels of nesting) in a more user-friendly and intuitive way than the standard WAB method of pop-up and attribute table?
There are some here that might help
No custom widget is needed, as I have discovered that version 2.3 of WAB (Developer Edition and ArcGIS Online) now shows related records (including multiple levels) in the pop-up - and without requiring use of the Atttribute Table widget.
The new related tables in the pop-up is just what I was looking for!
