Wish this worked but it doesn't

Please post a link to your site and I’ll take a look 🙂

Have you clicked “Enable” in the mega menu settings?

Hmm, looking at the CSS that max mega menu has generated, its enabled for the ‘header menu’ location.

But looking at the HTML on your page, it seems like the page is outputting the ‘main menu’ location.

Do you have 2 menu locations listed on the menu page? ( https://maxmegamenu.com/wp-content/uploads/2015/03/megamenu-theme-locations.png )

Where you have this code in your theme (probably in functions.php):

register_nav_menu( 'my_menu_location', ..... );

Please check the location in the wp_nav_menu call (probably in header.php) file matches up exactly:

wp_nav_menu( array( 'theme_location' => 'my_menu_location' ) );

Ah, I’m pretty sure that’ll be the problem then.

You’ll need to register a theme location (in your case it will be called something like header_nav) using register_nav_menu, then output the menu using wp_nav_menu (including the theme_location argument set to ‘header_nav’).

Ok then it you just need to modify the wp_nav_menu call to use that location.

Did you tag your menu to the location on the menu page? If not it will just show all pages by default.
