I know this is a newbie question and But I don't remember the trick or what I'm supposed to
be looking for.

I need to make the Quicklaunch Flyout and autohide on some sites and
not on other sites. I'm stuck at the moment not know where to start
looking. I know I can change the bahavior in my custom masterpage, but
I don't want multiple custom pages that will display the same set of
parts with the same data.

Please point me to a refernce, or to what I need to look at in the
Object Model.
