Uses Yandex Maps API (https://tech.yandex.com/maps/mapsapi/) or Google Maps API (https://developers.google.com/maps/documentation/javascript/) to find the address.
You can restrict the country and/or city (Yandex only) in which the address will be searched for each field separately. 
To restrict, you need to fill the default value attribute in the format <code>Default value : Country, city</code> (e.g. <code>Enter the address : Russia</code>, Moscow, <code>Your address : London</code>, <code>: Moscow</code>)
