How to add the relation field to layout in the studio?

Which relationship field? Is this one you have added, or a core out of the box field?

yes this is my question too .So basically i created a relation inside meeting with products.i can see product fields are available in subpanel in meeting’s studio view . Now i want some of the fields in subpanel in meeting layout view

Is it possible?
