Könnte mir jemand das erlären?
Ich habe jetzt noch andere Quellen nach Lösungen für dieses Problem durchsucht und bin auf diesen kryptischen Kommentar unter dieser Url http://trac.wordpress.org/ticket/1189 gestoßen:
cleared
Attached patch adds dropdown feature to wp_list_pages(). Usage:
wp_list_pages('style=dropdown');
First draft. Still rough.
Das ganze sieht so aus. Villeicht könnte mir jemand von euch erklären ob dieser Code funktionert bzw. wo ich diesen einsetzen soll.
Vielen Dank im voraus.
