List to List Wire schema and data model

Dear All ,

In custom objects do we have option to have header ( type 4) and item table in UI (type 4) ?

Generally we have all type 4 entities  having leading relationsship with type 1 . But our case is

one list UIBB ( Type 4 entity )  contains header details and we require another list UIBB which holds multiple entries for one row in first list UIBB .

Regards,
