Have a look at the Manager and Stack classes, I'm pretty sure that's what you're looking for. Stack has an internal Manager, which deals with keeping active state on only one controller at a time. It does that simply by adding the css class "active" to the currently active controller. From the docs: A Stack doesn't alter the display CSS property of its controllers, but rather simply adds and removes an active class. That explains what you're describing.
