Relational dropdowns in CMS

I'm developing a custom CMS for my client and he needs to select a CITY filtered by a COUNTRY.

i have:

class Country extends DataObject
  static $has_many = array(
  'cities' => 'City'

class City extends DataObject
  static $has_one = array(
  'country' => 'Country '

I'd like to have two separate dropdown fields (or something similar) and be able to dynamically filter the cities.
i've heard of 'FilteredDropdownSet' but it looks deprecated now (i'm using SS 3.4).

How can i do that? I really can't figure out

Thanks in advance
