Recursive form

[Amy Blankenship]

I have a client who goes completely crazy with his requirements. This means
that I have a hierarchical data structure that worked well for the original
project, but now he wants to "just" add this, that, and the other to it.
The upshot is that I need more levels of hierarchy than the data structure
can handle.

To deal with this, I've added two tables called PresentationContainer and
PresentationContainerItem. A PresentationContainerItem can either be
another PresentationContainer or it can be an object out of any one of four
tables (I've made this possible by creating a Union query that makes them
all "look" the same). The problem is that I need to create a form that
allows me to get to the items that are not containers, but in such a way
that makes their place in the hierarchy obvious.

So, I want to have

PresentationContainer Form
Subform Control
PresentationContainer Form or
PresentationContainerItem Form

and so on.

Is it possible to have a form embedded in a subform control that is the same
as the parent form? Any gotchas I should know about in advance?

Thanks;

Amy
