Answer 2

Country State Select is a library that provides a simple API for creating Country and State / Province drop-down lists for use in forms.

When implemented correctly, the State / Province drop-down menu is populated with the appropriate regions depending on the country that the user has selected.

After version 2.0.0 it also depends on simple_form 3.2

you can also find cities according to the state and name of the country using this gem
