Thank you for this answer.
So, what you say is that I can’t achieve that without creating a new field type… that’s something I’m not able to do as I’m not developer.
To get the idea, I want the user to choose a value in a list of choices and optionnaly add a comment. I need this comment to be linked to the field because the display will be not localised at the same place (so I need a reference).
