I can add information about companies in different countries to the company page. I did this using “Repeater,” inside which a list of countries was added using “Post relation” (countries were added as a separate post type).
As a result, a company representative adds data for each country to the page in a list, creating an informative table.
A large amount of such data is collected, and I need to display this data on the country pages.
But here a problem arises: when “Post relation” is added inside ‘Repeater’, there is no “Relation key” field, which means I cannot create a filter that would allow me to display the necessary information on the country pages.
I checked all filter options, but none of them can see the “Post relation” fields inside “Repeater”.
Creating a list of countries in the form of “Term” does not suit me, as then extra fields appear, and it is not possible to create a direct link by country name and back.
