navbar highlights

[Slavrix]

hi, ive gotten adding tabs to my navbar working using

http://xenforo.com/community/threads/add-own-navigation-tabs.5265/page-7

however im not sure how to go about making the tab stay highlighted when its the active tab.

<?php
class XenForo_myCustoms_myTabs
{

    public static function addNavbarTab(array &$extraTabs, $selectedTabId)
    {
        $extraTabs['irc'] = array(
            'title' => new XenForo_Phrase('myNavBar_irc_title'),
            'href'  => XenForo_Link::buildPublicLink('pages/irc'),
        'selected'  =>  ($selectedTabId == 'irc'),
            'linksTemplate' => 'myNavBar_irc_title',    
            'position'  =>  'middle'
        );
    }
}

thats my class

ive made a new listener which works fine also, the tabs all work, its just they dont stay highlighted when i click them
