i want to disable default menu class, bellow code is disable menu class completely. 

add_theme_support( 'menus' );
add_filter('nav_menu_css_class', 'my_css_attributes_filter', 10, 1);
add_filter('nav_menu_item_id', 'my_css_attributes_filter', 100, 1);
add_filter('page_css_class', 'my_css_attributes_filter', 100, 1);
function my_css_attributes_filter($var) {
    return is_array($var) ? array_intersect($var, array('current-menu-item', 'current-menu-ancestor')) :
    '';
}

but now issue is when even i add custom class in menu

enter image description here

example navcon that class not coming. i understand a bit it because of add_filter('nav_menu_css_class', 'my_css_attributes_filter', 10, 1); so is there any way just disable all defualt class but if have custom class then it will add

my trample code is <?php wp_nav_menu( array('menu' => 'mainmenu','items_wrap'=>'%3$s', 'container' => false)); ?>

    Dump the value of $var inside your callback. Then edit your question and show the output.

  • Add a var_dump( $var ); in your my_css_attributes_filter function and add the output to the question.

  • Sorry, but this is going nowhere this way… The only thing that can help you is a copy/paste solution which you won't find here. You are better off when you search and pay a developer to help you solve your problem.

i got a answer from another thread.. which is bellow

    add_filter('nav_menu_css_class', 'discard_menu_classes', 10, 2);


function discard_menu_classes($classes, $item) {
    $classes = array_filter( 
        $classes, 
        create_function( '$class', 
                 'return in_array( $class, 
                      array( "current-menu-item", "current-menu-parent" ) );' )
        );
    return array_merge(
        $classes,
        (array)get_post_meta( $item->ID, '_menu_item_classes', true )
        );
    }
