i want to change menu when a search is done to display several modules i have i suppose the order is
<?php $this->menu_id = '&Itemid=102'; ?>
but where do i have to insert this param

and also when you click on a searched product need to force a menu too because the sidebar menus does not display

Hi,

In the your seach module options, you can set the Itemid, the option is "Set ItemID".
