How to link two posts in Wordpress?

Question

WordPress

There are two types of records: Countries and Cities, respectively, in countries I add new countries, and in y-> y. It is necessary for me that when adding a city, I could select a country (such as a category). Maybe there is some plugin?

Answer 1

either make 1 record type a city and categories for it in the form of countries,
or leave it as it is and link it through the acf plugin
