Ein großes Lob an die Entwickler!
Aber nun zu meinem Problem:
Ich habe die Navigation aus der Demo entnommen und etwas angepasst, nun möchte ich eine dritte Ebene einfügen. Die aufklappt, wenn man einen Link der zweiten Ebene anklickt.
Leider bekomme ich folgenden Error ausgegeben:
Fatal error: Call to a member function getChildren() on a non-object in D:\xampp\htdocs\redaxo_2\redaxo\include\classes\class.article.inc.php(443) : eval()'d code on line 64
