Display related item fields

Hello,

I want to display in an item, a sidebar displaying fields from the parent item (relation).

In the parent item, I have 3 important fields :

• A fieldgroup (multiples values)

and inside the fieldgroup :

• Title of the group
• Item in relation (multiple values)

Check in the attachment what I try to achieve, sort of a menu with related items (the view is the child view because we need to navigate in these).

I was only able to get the titles of the groups with some of the code here , but I can't have a tree structure.

I've seen there's an extension to do the task but it seems completely outdated.

Thank you very much.

Hello

the fieldgroup field has a parameter to customize its HTML display
furthermore you can even create a custom layout for it and select it the fieldgroup field configuration

Oh indeed I successfully did that with {{section##0}} in the field.

Now I need to create a custom layout for that field. Thank you ggppdk
