Address configurator - Fields Hide allows you to set fields in customer address as hidden, optional, required or leave default Opencart behaviour. Module can be used on these fields: telephone, fax, company, address 1, address 2, city, postcode, country and zone. If you hide country or zone, it will be filled with values from store settings. Module affects customer registration, data and address editation, checkout (both guest and registered customer) and backend customer administration.
