You could separate your menu into two main items(pages), called hmenu and vmenu.
Place all of your current pages under the hmenu item and create your new catalog pages under the vmenu item.
Call the hmenu on your horizontal top menu and vmenu on your side menu.
I do it like this:
Code: Select all
<div id="menu_horiz">
<h2 class="accessibility">Navigation</h2>
{menu template='cssmenu.tpl' start_level='2' start_element='1.1' show_root_siblings='1'}
<hr class="accessibility" />
</div>
<div id="menu_vert">
<h2 class="accessibility">Sub Navigation</h2>
<ul><li>{menu template='simple_navigation.tpl' start_level='2' start_element="2.1" show_root_siblings='1'}</li></ul>
<hr class="accessibility" />
</div>
