how to add custom wp_nav_menu class css selector to ul and a tags?

Question

crafting a theme from finished html/css markup and wonder how to wrap a tags in my custom class? With ul wrapper this is works:

            wp_nav_menu(
                array('menu' => 'menu-header',
                      'menu_class' => 'list',)
            );

but how to deal with menu items, and with currently selected menu item? I need ul to be with .class selector and li with .item selector as well

Answer 1

The following example adds a unique CSS class to a single, specific nav menu item.

function my_special_nav_class( $classes, $item ) {

    if ( is_single() && $item->title == 'Blog' ) {
        $classes[] = 'special-class';
    }

    return $classes;

}

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

Answer 2

ok this is too trivial, all i was need it a filter on nav_menu_css_class
