AFAIK, not possible. The closest you would come is either tabbed forms, which would put them side by side, or have the other forms pop up modal to see whatever is related to whichever you consider the prime form to be, so the related data can be seen. Why are there so many other tables involved? You can't base the form on a query that joins them and show the related data in one form or a form with a minimal number of subforms? Not saying it's so, but when someone posts that there's too many tables or fields involved, it's usually because of improper normalization.
The more we hear silence, the more we begin to think about our value in this universe.
