A One-to-Many form can be a child Related Form, but the Parent Mode functionality of the Toolbar is disabled for technical reasons involving the child grids.

A form that contains an editable grid constructed with the ProMatrix Grid Builder (see ProMatrix Grid Builder – an Editable Grid) can be a child Related Form if it’s set up properly.
