I'm trying to build a simple one page app where i have more than one 'Headers' & 'Footers. Just like once can togglee between PopUps / Panels, is it possible to toggle Headers/Footers using Action Framework ?
One way to do what you want might be through a UI-only model and conditional rendering. You could put rendering conditions on your headers and footers, and then show or hide them based on the value of UI-only fields on your UI-only model (that you could update through the action framework). It would be similar to example #1 in the tutorial I linked to.
