I need to transform state field in a list of state but not limit the country

how can i turn the state field into a list of states by keeping the selection free for nations? in the documentation it explains how to set up a specific country and then create a list of states. but it does not explain how to leave nations free and the list of states to turn it into a list anyway.

I’m not sure what you’re looking for exactly. Can you share a screenshot or example of what you mean?
