Enter multiple domain values in one field

[KimberlyWinter]

Can we allow mutliple domain values in one field i.e. often we have in forestry multiple different species in one subcompartment. It is impossible to add all of these different combinations as part of a domain but we require data standardisation. 

If you could choose SS / LP/ MB with 'SS' 'LP' and 'MB' all as separate domain values it would ensure the data is standardised without having to add every combination within the domain.

I don't know if it would make sense in your workflow, but you might want to consider using a Survey123 form as your data entry mechanism. Survey123 forms allow multi-select questions and then store the response as comma separated values in a single field.

And following along with @HollyTorpey_LSA's point, you can build similar functionality within Forms via @Woodpecker 's solution in this idea page Multiple choice option in Field Maps - Esri Community

I have tested it and it seems to work fairly well in trying to convert some of my Survey123 surveys into Smart Forms (in some cases the clearing values might take a minute or so to recalculate to blank with the way I had set it up).
