After some researched I realized there's no support for editing related tables using Web AppBuilder, this is a feature strongly necessary in our organization since we have a ton of tabular data related to polygons.
My question is if this is possible to achieve through a custom widget? And how difficult would it be to be able to see all related tables to a polygon, edit and add new data to these tables. We want to maintain an enviroment with low maintenance and IT support dependency, so making a javascript application from scratch is not ideal
