Custom CSS classes and IDs for Genesis menus

July 28, 2012 By David Wang

Here’s a quick code snippet to:

Assign an ID to the menu
Change the menu class
Append to the menu class

add_filter( 'genesis_do_nav', 'override_do_nav', 10, 3 );
function override_do_nav($nav_output, $nav, $args) {

    $args['menu_id'] = 'the_id_you_want';
    $args['menu_class'] = 'class1 class2'; // replace what was there
    $args['menu_class'] .= ' class3'; // or append to it

    // check which function should be used to build the nav
    // rebuild the nav using the updated arguments
    if ( genesis_get_option( 'nav' ) ) {
        if ( has_nav_menu( 'primary' ) ) {          
            $nav = wp_nav_menu( $args );            
        } elseif ( 'nav-menu' != genesis_get_option( 'nav_type', 'genesis-vestige' ) ) {
            $nav = genesis_nav( $args );
        }
    }

    // return the modified result
    return sprintf( '%2$s%1$s%3$s', $nav, genesis_structural_wrap( 'nav', 'open', 0 ), genesis_structural_wrap( 'nav', 'close', 0 ) );

}

Force Superfish menus

March 20, 2012 By David Wang

Force the Superfish script to be activated on navigation menus using the genesis_pre_get_option_ filter.

add_filter( 'genesis_pre_get_option_nav_superfish', 'nrp_get_option_nav_superfish' );
function nrp_get_option_nav_superfish( $opt ) {
	$opt = '1';
	return $opt;
}

Tip: Use this in conjunction with removing unused theme settings metaboxes so that users are not confused with why their settings are not being saved.
