MAL has a module which you can use to replace the original mainmenu but what if you want to use other menu's like topmenu etc? Here we are describing what we do in our mal_mainmenu module so you can use this example to alter the other menu's

Change
// establish the hierarchy of the menu

To
// establish the hierarchy of the menu
$skip = array(); //konlong added for access test

Before the line $menu_style = $params->get( 'menu_style', 'vert_indent' );
5) change all function calls with mos* to mal*.
Example mosShowVIMenu to malShowVIMenu
Or change the corresponding calls in our routines to the original mos* function.
