[size=4]Anpassen des Skins[/size]

Im Ordner Addons/Skin/s1 befindet sich die Datei mod_collapse_skin.php. Hier ist ein Ersatz der [b]Originalfunction CatHeader_Expanded(...)[/b]. Die neue Funktion fügt eine kleine Grafik zum Header jeder Kategorie hinzu, so dass die Kategorie durch Anklicken verborgen werden kann.

Diese Datei kann angepasst und in den Skinordner ./Skin/sx kopiert werden . Nicht vergessen, ein Resynchronize via ACP durchzuführen.
