/**

|
* 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>
|
|
* </div>
