The ArcGIS Collector edit popup needs to be customizable, similar to how the display popup is customizable with the Custom Attribute Display option.
Essentially, our field teams need more on screen information to fill out each field in a new feature. We need a note before each attribute so the field worker has the relevant information to fill out the attribute correctly. Ideally this note would be dynamic, displaying different information based on other attributes.
All that needs to be done is apply the Custom Attribute Display to the edit popup. Then we can use custom expressions to generate the necessary text.
