Hi colorit2,
According to the link you posted above you will have to place code in header.php. Keep in mind I've never done this so I'm just going by the article you linked above so this may or may not work.
Open you header.php and replace this:
<!-- Navigation for Pages starts here -->
<?php
wp_nav_menu( array( 'menu' => 'First', 'menu_class' => 'nav', 'echo' => true,
'fallback_cb' => '', 'before' => '', 'after' => '', 'link_before' => '', 'link_after' => '',
'depth' => 0, 'context' => 'frontend'));
/* pre wp 3
if(is_object($k_option['custom']['kriesi_menu_pages']))
$k_option['custom']['kriesi_menu_pages']->display('Menu Manager Pages','show_basic');
*/
?>
with this:
<?php
wp_nav_menu( array(
'theme_location' => 'primary',
'depth' => 0,
'walker' => new description_walker())
);
?>
Again, I haven't test this so I'm not sure if it will work or how well it work.
Regards,
Mya
