* Vertical CMS menu with two levels, built from a nested unordered list.
* The (optional) second level is collapsible, hiding its children.
* The whole menu (including second levels) is collapsible as well,
* exposing only a preview for every menu item in order to save space.
* In this "preview/collapsed" mode, the secondary menu hovers over the menu item,
* rather than expanding it.
*
* Example:
*
* <ul class="cms-menu-list">
* <li><a href="#">Item 1</a></li>
* <li class="current opened">
* <a href="#">Item 2</a>
* <ul>
* <li class="current opened"><a href="#">Item 2.1</a></li>
* <li><a href="#">Item 2.2</a></li>
* </ul>
* </li>
* </ul>
*
* Custom Events:
* - 'select': Fires when a menu item is selected (on any level).
