[codek]

Hi all, im working on modify a prestashop papple theme. ( http://www.goldenphone.es/tvirtual )

 

I want to change the category left column module. What I want is to click on a category, for example clicking on "Informatica" category have the same effect as clicking the "more" button ( http://goldenphone.e...g/icon/more.gif ) and so that when click on a category display the submenu of "Informatica".

 

So, do not take you to the category "Informatica" ( http://goldenphone.e...l/8-informatica )

 

Thanks and sorry for my bad english.

 

Regards
