Field is based on nova-ajax-select. But instead of providing api endpoint, you can fill options by a closure function.

            Select::make('Country')
                ->options(Country::all()->pluck('id','name')
                ->rules('required'),

                ->parent('country')
                ->options(function ($value) { 
                    City::whereCountry($value)->get()->pluck('id','name')
                })
