[I.am]

This is what i use

PHP Code:

$tabselected = '';
$tablinks = '';
if (THIS_SCRIPT == 'Downloads')
{
    $vbulletin->options['selectednavtab']='Downloads_tab';
    $tabselected = ' class="selected"';
    $tablinks = '                <ul class="floatcontainer">
                        <li><a href="/resources/">Downloads</a></li>
                            <li class="popupmenu">
                                <a href="javascript://" class="popupctrl">Drop Down</a>
                                <ul class="popupbody popuphover">
                                        <li><a href="sublink1.php">Test Link 1</a></li>
                                        <li><a href="sublink2.php">Test Link 2</a></li>
                                        <li><a href="sublink3.php">Test Link 3</a></li>
                                </ul>
                            </li>
                        <li><a href="link2.php">Link 2</a></li>
                        <li><a href="link3.php">Link 3</a></li>
                </ul> ';

} 
$template_hook['navtab_end'] .= '<li'.$tabselected.'><a class="navtab" href="http://mysite.com/resources/">Downloads</a>'.$tablinks.'</li>' ; 


But when the page is selected the button doesn't work properly.
