I want field with entity reference showed as select but based on value from the another field in the same form [radio button field] for example the entity reference field will list these values
and the field radio button will hold countries like so:
notice that the entities reference (Content Type) has field called country, so when i check the value "England" i want the field entity to be filtered based on England for ex: -entity 1 & -entity 4 and same if i clicked Germany.
is that applicable in Drupal 7 even by Views module, or i have to do it custom !?
