APEX

I have one lookup table that stores multiple lists (countries, nationalities, currencies…) using a major/minor setup (major = list id, minor > 0 = values).

Example SQL:

SELECT CASE 
	WHEN :APP_LANG = 'en' THEN list_display_en
	WHEN :APP_LANG = 'ar' THEN list_display_ar
       END AS D
     , list_minor AS R
  FROM app_lookup_master
 WHERE list_major = 10
   AND list_minor <> 0 ;

I want to reuse one shared LOV and just pass the list_major value (e.g. 10 for countries, 20 for nationalities) instead of hard-coding it.

Question:
How can I pass a parameter (page item or application item) into a shared LOV so it filters by the right major value? Is there a clean way to do this?
