How to retrieve list values element by element

Hi,

I have a repeating group which retrieves values from a list, I want to display a single value in each cell “Not repeated”.

Extra:
How to link a single value from the list to another type by using Checkboxes?

Why don’t you make that list a type on it’s own and display that?

Because it is related to 3 different categories (each of them has its own list) which are a sub-category of the type.
