I have a hosted feature layer that has a domain field for street light status, i.e. operational, not operational, day burner, etc. When I am editing in the Web Map I created I have a drop down selection from the domain. I created a Web Mapping Application using the Editing template to use with Collector, however the field that uses the domain no longer has the drop downs. Instead it is like a text field where you are able to type in the field.
I am new to the ArcGIS Online realm.
