Verwenden von wp_list_categories oder einer anderen function innerhalb eines Menüreiters?

Ich bin neu in WP mit Menüspaziergängen herumzuspielen, also versuche ich vielleicht etwas zu tun, was nicht möglich ist, ich bin mir nicht sicher.

Was ich versuche, ist ein Div einzufügen, das eine Liste meiner Produktkategorien in einem bestimmten Menüelement enthält. Ich habe einen Walker, der arbeitet, um das Listenelement zu zielen und meinen Wrapper einzufügen, aber ich kann nicht für das Leben von mir herausfinden, wie man meine wp_list_categories function in diese Ausgabe hinzufügt. Hier ist was ich habe:

class Custom_Nav_Walker extends Walker_Nav_Menu { function end_el( &$output, $item, $depth = 0, $args = array() ) { if ($item->object_id == 128) { $output .= ""; $output .= "\n"; } } } 

Wie kann ich eine function in die $ -Ausgabe einfügen? Denke ich darüber alles falsch?

Danke für jede Hilfe!
