I believe wp_nav_menu() handles the top-level list wrapping so start_lvl method would only handle submenu items ( from my understanding ). It also doesn’t give us access to the $item which we need to get the parent. Below I’ve setup a boolean variable to track whether we should be showing our title or not. It … Read more
You could try to use the wp_nav_menu_args filter (untested): /** * Add the Menu_With_Data_Attr walker to the wp_nav_menu() used by genesis_do_nav() */ add_filter( ‘wp_nav_menu_args’, function( $args ){ if( isset( $args[‘menu_class’] ) && ‘menu genesis-nav-menu menu-primary’ === $args[‘menu_class’] ) { if( class_exists( ‘Menu_With_Data_Attr’ ) ) { $args[‘walker’] = new Menu_With_Data_Attr(); } } return $args; }); to … Read more
just been reading an article on removing <li> elements from wp_nav_menu (http://css-tricks.com/snippets/wordpress/remove-li-elements-from-output-of-wp_nav_menu/) and the code suggested is $menuParameters = array( ‘container’ => false, ‘echo’ => false, ‘items_wrap’ => ‘%3$s’, ‘depth’ => 0, ); echo strip_tags(wp_nav_menu( $menuParameters ), ‘<a>’ ); have you tried this ?

How to add ID and class in nav menu walker?

Your menu doesn’t appear to have any levels. start_lvl and end_lvl are used for the sub-menu wrappers. The outer wrapper for the menu, the <ul> is defined by the items_wrap argument of wp_nav_menu(): wp_nav_menu( [ ‘walker’ => new My_Walker(), ‘items_wrap’ => ‘<nav id=”%1$s” class=”%2$s”>%3$s</nav>’, ] );
I can confirm that this filter applied with 3 parameters as you mentioned in your snippet. The warning is very strange and shouldn’t appear if WordPress core wan’t hacked.
