/*
The action menu is a menu that usually belongs to an OpenProject entity (like an Issue, WikiPage, Meeting, ..).
Most likely it looks like this:
<ul class="action_menu_main">
<li><a>Menu item text</a></li>
<li><a>Menu item text</a></li>
<li class="drop-down">
<a class="icon icon-more" href="javascript:">More functions</a>
<ul style="display:none;" class="legacy-actions-more">
<li><a>Menu item text</a></li>
</ul>
</li>
</ul>
The following code is responsible to open and close the "more functions" submenu.
