Maximum number of choices for select_one? External source possible?

[DirkVandervoort]

Putting aside the discussion of degrading the user experience by allowing hundreds of choices on a phone in a select_one, is there a limit to the number of choices a survey designer can add?

Along the same lines, is it possible to have the data source for a select_one be in external csv file? I see you can do that for cascading selects...

But let's just say - for the sake of discussion - I want my users to select one from a couple of hundred choices (e.g., utiliity poles). Good? Bad? Or just plain ugly?

TIA

As Ismael's reply indicates, the best method to handle that many choices is via an external select, which moves the choices to a separate file that is loaded when a previous question is answered.  See Cascading and external selects—Survey123 for ArcGIS | ArcGIS for more information.
