Easy...
Replace this line of code in the clearance.tpl file:
Code:
{include file="dialog.tpl" title= "Clearance Items" content=$smarty.capture.clearance_list extra="width=100%"}
with this:
Code:
{ include file="menu.tpl" menu_title="Clearance Items" menu_content=$smarty.capture.clearance_list }
And don't forget to place this code:
Code:
{include file="customer/main/clearance.tpl"}
in the home.tpl file so it appears where you want in the menu section.
Hope this helps!
