I'd be grateful if someone could spare a few minutes to help me out, I've read and re-read how to solve this but I've not confidence in editing the core template code.
<!--End Header-->
<div id="page-bg"><div id="page-bg2">
<div class="wrapper">
<!--Begin Horizontal Menu-->
<?php if($mtype != "none") : ?>
<div id="horiz-menu" class="<?php echo $mtype; ?>"><div id="horiz-menu2"><div id="horiz-menu3">
<?php if($mtype != "module") : ?>
<?php echo $topnav; ?>
<?php else: ?>
<jdoc:include type="modules" name="toolbar" style="none" />
<?php endif; ?>
<div class="clr"></div>
</div></div></div>
<?php endif; ?>
<!--End Horizontal Menu-->
<div id="vertical-sort">
<?php
echo $section_rows->render();
?>
</div>
</div>
<!--Begin Bottom Section-->

States to put a container around the navigation, but there are so many divs I'm unsure.
Adding in #menu-container {position:relative;z-index:99;} into the CSS I'm happy enough doing (although someone suggests changing 99 to 9999)
Grateful for any assistance.
