We have a trees layer with over 200 subtypes (one for each tree species) in a field called NameType. Each subtype changes six other fields: SPcode, Genus, Species, Cultivar, SciName and ComName. We're creating a web app to allow editing for field crews with ToughBooks. Currently the field only shows the subtype code plus there's no dropdown to pick other subtypes. For editing to work properly, we need to be able to see a dropdown of all subtype descriptions (not codes, which are meaningless to users) and when one is picked, the other six fields should automatically change. Does anyone know if this even possible with AGOL and if so, does it require custom code?
