We want to see this in the standard web map popup. So it looks to be supported out of the box now which is great! Just enable the fields in the Configure add {relationships/xx/fieldname} as posted in various threads here.
The weird thing is, I have a related service Layer: CIP Projects by Category (ID: 0) . The field names display in the popup but not the records data itself. It works just perfectly, but only in the Attribute Table widget though!
It needs to be in popups so that it works in the Short List. The Story Map 'Short List' app which is an awesome viewer template. But it takes the popup info and puts it into the sidebar div on the left. So that won't work until the info shows up in the popup.
Long story short, pun intended, we'd like to see related records in the Short List Story Map's sidebar. Anyone else gotten that to work? Did I run in to a ArcGIS Online bug or maybe I didn't configure the relate and SQL view right? This is the first time I've worked with views or relates in a web map.
