make parent link active in

I am using this plugin:
http://wordpress.org/plugins/jquery-vertical-accordion-menu/
I createt great accordion menus but I want the parent link to be clickable in addition to the submenu open, and lead to the page. I guess I need to add a fonction to the JS but I don’t know how to do it.
