Die Hauptnavi1.1-1.2 von Jan Legowski aus der 4.5 mit 4 Ebenen läuft in der 4.4 nicht, weil die Funktion isStartarticle hier nicht existiert. Das macht aber nichts, denn man braucht diesen Teil des Codes nicht übernehmen, sondern nur den Teil ab /* Start Output buffer */ . Die Änderung ggü. dem Orginalcode aus der 4.4 fügt lediglich eine weitere Verschachtelungsebene ein. Eigentlich braucht man nur diese zusätzliche Schachtel, aber so ist´s einfacher. Ich vermute, man könnte an dieser Stelle auch noch tiefer verschachteln - wer´s braucht.
Jedenfalls, ich hab´s bei mir getestet und es läuft einwandfrei. Die Konfiguration braucht auch nicht geändert werden. Einfach den Code ins Modul schmeissen und fertig. Ach ja, nicht vergessen, auch im Verzeichnis templates die beiden Dateien navfourth_on.html und navfourth_off.html anzulegen und ggf. dort die CSS-Formatierung für die 4. Ebene zu machen bzw. eine CSS-Klasse einzubinden.
Der Input-Teil kann unverändert bleiben. Für diejenigen, die das Modul nicht haben, poste ich einfach den kompletten Code des geänderten Moduls:
