Add options to a feature?

How would one add options or variants to a feature? If an option is created and variants assigned, how can this be associated with a feature? Is this stuff documented anywhere?

For example, I created an option named “power source” and added variants. No way that I see to assosciate it with a category or anything else.

Thanks for any insights on how this menu works.

I had the same problem.

The thing I did was make sure “Type” in the Add Feature popup screen is “Select Box>Text”

Thanks. Will give it a try.
