Changing default theme Menu behaviour

[NV1]

Hello everyone,

 

I have setup a shop with default theme. And, I would like to change the default menu behaviour. 

 

Right now when I move my mouse over the category say "WOMEN", all levels of subcategories are displayed. i,e Sub categories of "WOMEN" - "Tops", "Dresses" are displayed. Also, sub categories of "Tops" - "T-Shirts", "Blouses" are also displayed. 

 

I would like to get the sub categories displayed only if I click the link. 

 

i,e only if click the link "WOMEN", "Tops" and "Dresses" should be displayed. Only if click the link "Tops", "T-Shirts" and "Blouses" should be displayed. 

 

I am not sure where to change that - in superfish-modified.css or blocktopmenu.php

 

Can someone pls. help?
