I've been running through this type of issue for quite a bit of time and would like to know if it could be possible to allow names with spaces in multiple choice selects, as well as allowing to store this data with spaces between each selection (e.g. "Option 1, Option 2, Option 3", rather than "Option1,Option2,Option3"). This will be highly beneficial when producing reports or tables that contain this information.
Is there possibly a way to pull the data out of the select_multiple field and reformat it with spaces into another field? I'm having the same issue as Javier. When creating reports in ArcGIS Pro the lack of spaces is problematic.
A possible work around would be to have a calculate field for each choice that is populated if a given choice is selected - that would allow you to populate whatever text you would want.
James can you expand on this? I have an inspection survey that has a multiple select that needs to store the same values as the web application that we are integrating with. Basically we need Survey123 needs to be able to pass the values into one field as a comma delimited string with spaces.
