Add thumbnail

Hi Graphik Impact,

While there is no direct way to filter each menu item as it’s being rendered, you may override the Walker using this plugins’ filter and render each item manually.

use Advanced_Sidebar_Menu\Walkers\Page_Walker; class ASM_Featured_Image_Walker extends Page_Walker { protected static $attributes = []; protected static $classes = []; public function __construct() { static $hooked = false; if ( ! $hooked ) { add_filter( 'page_css_class', [ __CLASS__, 'store_css_classes' ], 9999 ); add_filter( 'page_menu_link_attributes', [ __CLASS__, 'store_attributes' ], 9999 ); } $hooked = true; } public static function store_attributes( $atts ) { self::$attributes = $atts; return $atts; } public static function store_css_classes( $classes ) { self::$classes = $classes; return $classes; } public function start_el( &$output, $page, $depth = 0, $args = [], $current_page = 0 ) { $li = ''; parent::start_el( $li, $page, $depth, $args, $current_page ); $attributes = ''; foreach ( self::$attributes as $attr => $value ) { if ( is_scalar( $value ) && '' !== $value && false !== $value ) { $value = ( 'href' === $attr ) ? esc_url( $value ) : esc_attr( $value ); $attributes .= ' ' . $attr . '="' . $value . '"'; } } $args['link_before'] = get_the_post_thumbnail( $page->ID ); $output .= sprintf( '<li class="%s"><a%s>%s%s%s</a>', implode( ' ', self::$classes ), $attributes, $args['link_before'], /** This filter is documented in wp-includes/post-template.php */ apply_filters( 'the_title', $page->post_title, $page->ID ), $args['link_after'] ); } } add_filter( 'advanced-sidebar-menu/list-pages/parse-args', function ( $args ) { $args['walker'] = new ASM_Featured_Image_Walker(); return $args; } );

Have a great night!
