I'm not sure I understand the use case exactly.

If you just mean that you have several different "panels" or "modes" that 
the user can switch between, then I would recommend just having several 
<section> elements, one for each module, and all but the active one have a 
hidden="" attribute. Script-wise, you'd just have each script loaded and 
active from the start, they'd just only work with their own sections.
