UI Only Reference Fields - Documentation??

Hi, DDeveaux,
I think a little more clarity on your use case may be helpful…

So you have a Ui-only picklist field (currently built with a JS snippet) that you’re using to populate data on a new Contact record, and it sounds like the options for this field are being sourced from multiple Account fields? Are these multiple Account fields what “field1, field2, etc.” correspond to?

What field type are the fields on the Account object? Picklist, reference, string, etc…?

Are you trying to bring all field options from the Account fields into a single picklist field for the user to select from (i.e. Bring values from field1, field2, etc. into a single picklist field), or multiple picklist fields (i.e. Show one field to the user for all values from field1, another field for all values from field2, etc.)?

Hope those questions make sense.
Thanks!
Emily
