Subform looks in form view/mode

Subform looks in form view/mode

I have a form with subform, and I want to have the subform to be showing in the same design as the form. Currently it shows as a list inside of the form.

Like when I crate a lookup field, and click on +Add link next to the lookup field, it opens a new form on top of the main form. That's how I want the subform to work.

Please let me know if that's possible to arrange.

Thanks,
Anri
