The CollapsiblePanelExpander, as the name implies, allows us to easily add
collapase and expand functionality to any section on the sites that we build
with Atlas. Here is a quick look at some of the different ways that we can build collapsible panels using this robust extender. You can check out the five quick demos and the
accompanying source code. I've also made the website project available.
The code should be really self-explanatory, so there's no indepth explanation
like my previous posts on Atlas.
