I am looking for a widget that let's the user select a polygon feature by a a value and then use that selection as the basis for a spatial query to find all the point features within that polygon.
I see a few options out there, but most deal with map extent or a user drawn shape. Am I missing something obvious or do I need to write something? I see there is a new District Lookup widget in AGOL, but from what I can tell, it's based on an existing data relationship, not an on the fly selection.
