Adding Hover Menu Items

[tcarter01]

I've inserted the following code in Hook Location location process_templates_completion. The menu appears but the submenu items don't appear until its clicked. Is there a way to change this so that the items appear as you hover over them without the click?

$template_hook['navtab_end'] .= '<li class="popupmenu">
<a href="javascript://" class="popupctrl navtab">Menu Test</a>
<ul class="popupbody popuphover">
<li><a href="sublink1.php">SubLink 1</a></li>
<li><a href="sublink2.php">SubLink 2</a></li>
<li><a href="sublink3.php">SubLink 3</a></li>
</ul></li>' ;

TIA,
Tony
