Mostrar subcategorias de modo vertical en en top menu

[josue.sanz]

Buenas tardes, quisiera saber si me podrían ayudar a modificar mi menu superior, quiero que las subcategorias se vean en forma vertical, no horizontal como esta ahora.

 

La direccion de la pagina es http://www.joyaplata.com.mx/index.php

 

El codigo de mi archivo superfish-modified.css es el siguiente:

 

Muchas gracias de antemano
