Does Survey123 allow you to populate select_one choice lists from an external database or a feature table in ArcGIS Online?
I've worked with the pulldata() function which can populate lists from static data stored in a CSV, but my current scenario requires a dynamic data source.
Choice lists are essentially coded values in ArcGIS and these are configured and stored in your feature layer's configuration, so there is no getting around that.
Hope this helps.
This is coming in the new version, 3.12, of 123 due out this month. You can also join the Early Adopter program to try it now.
Dynamically loading choices from feature services
The search() appearance allows you to query ArcGIS feature services and populate choice lists based on the results of the search query. When using the search() appearance with ArcGIS services you can use @geopoint, @geotrace, and @geoshape for the searchColumns depending on the geometry of the feature service you are querying.
For search type the following searchTypes are supported, this list comes from the spatial relationship parameter when querying a feature service or layer :
This assumes being online of course. There will also be a way to link to online csv files.
Hope that helps
No you can manually, or with script, upload a new CSV to AGOL directly also. I have not used it so not well versed.
