Menú y submenú

[charlyta]

Hola! Este script lo utilizo en un menú css. Me activa la clase del menu que es la página actual, pero quisiera que también me activara la categoría en la que se encuentra o bien, de no ser posible, activar la categoría en función del directorio.

Me echáis un cable? Mil gracias
