/**
|
|
* 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).
