Choisir la "related" dans une vue de détail

[Romain_GICQUEL]

Hello,

In the detail of a view, I have the opportunity to insert a “related” view.
The problem is that I cannot choose what I would like.

On the attached print screen, you will see in red what is offered to me and in green what I would like.
Could you tell me how to do it?

Thank you
