This question refers to the standard ArcGIS Online map, eg http://your-site.maps.arcgis.com/home/webmap/viewer.html
Is it possible to perform a Select By Location, eg to find points from one layer which fall within a polygon layer?
There are a bunch of operations available under the Analysis menu but I can't see Select By Location. Is it necessary to build something custom (eg using the ArcGIS JS API, Web AppBuilder, etc) in order to get the Select By Location functionality?
