Radial select question option

[ellipsol]

I'm working on a survey and I want users to have some radial select ("Single select") questions where the options are Yes, No, or Unknown. The responses should write to a field in an existing feature layer. 

Right now, I only see the "Slider" as an alternative option when the field is an integer. I've tried with string fields, but only see the "Singleline text", "Multiline text", and a few other unneeded options. Do you know how I can see a  "Single select" option when I drag in a field?

Below is a screen capture of the options for an integer field.

I want to have a "Single select" option where the results write to a field. I'm working in survey123.arcgis.com.

Is this not available to you?  There should be an option in the choice section for Single Select.

It's available yes, but I can't seem to get it to populate an existing field in my feature layer.

I try to reverse engineer it by first adding the field to the survey, but I don't see a "Single select" option.

Gotcha.  I think this is because the field does not have a domain associated with it. You can try one of these to add a domain and then it should show as a choice select. At least with my quick test.  I did have to recreate the form from the test layer to get it to show correctly...

Thank you for your efforts. I had created a domain for the field, but at your suggestion, I re-created the form using that layer. I still don't see the "Single select" option for that field. Below is my domain.

@ellipsol strange, when I test it after adding a domain and refresh appears automatically as a single select.  What does it say for that field on your schema page.

Oh you did a string type, I will try that.

That did it, using a string field! Many thanks.
