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="action_menu_more">
|
|
<li><a>Menu item text</a></li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
The following code is responsible to open and close the "more functions" submenu.
