xtcommerce Navigation verändern

[Peet]

Hallo zusammen,

ich hab mal ne frage bzgl der navigation (also links wo alle kategorien stehn).

Wenn man eine Kategorie anklickt (und sich darunter das submenü öffnet) sollen alle anderen Kategorien verschwinden, dass nur noch das eine mit dem submenü dasteht.
Geht das irgendwie und in welcher php muss ich da was verändern?

Im Moment is alles im Navigation auf standard (außer CSS) DER SHOP

hier die Datei die das regeln müsste:

<?php
