/**
* Vertically collapsible panel. Generic enough to work with CMS menu as well as various "filter" panels.
*
* A panel consists of the following parts:
* - Container div: The outer element, with class ".cms-panel"
* - Header (optional)
* - Content
* - Expand and collapse toggle anchors (optional)
*
* Sample HTML:
* <div class="cms-panel">
* <div class="cms-panel-header">your header</div>
* <div class="cms-panel-content">your content here</div>
* <div class="cms-panel-toggle">
* <a href="#" class="toggle-expande">your toggle text</a>
* <a href="#" class="toggle-collapse">your toggle text</a>
* </div>
