A selection can have a personalization (title x text)
A selection can have many articles
So all information can be added to each table. When I create a relation some of the data do not get duplicated as I have no match. I don’t how to do that.
Can you show us how you’re structuring your tables, especially your relations in some screenshots?
You should be able to have 3 tables:
Users table: with a column to house your choice. Your choice should be powered by a choice component, with multiple choices enabled. You should write selections’ IDs for this, not their actual names.
Selections table: title, text, relation to Articles table.
Articles table: Selection ID, plus any other info you need for an article.
