What alternatives are there to creating a Single Select field option in a form interface?

[Ruchika_Abbi1]

I have a Single Select field field that I want to allow users to be able to add new options too when they are in Create Form interface. Since this is not possible, are there any workarounds/alternative designs that anyone has used?

My thoughts:
1. Using Linked Record is also not possible, since it doesn't allow new record creation from the Create Form interface. 
2. Using a text field and then automating creation of the option in Single select also is not possible since I believe it doesn't allow update of the Single Select options through "Run Script" in automation?

Regarding the interface side of things, ideally workarounds aren't needed and they just include this basic option already present for multi-select fields (but not for single-select fields, which doesn't make sense to me.)

Oops, yep I missed that!

That’s so strange that Airtable offers that for multi-select fields but not single-select fields. Be sure to send that as a feature request to support@airtable.com
