[jQuery] Superfish : Slide doesn't work

[Fabinou]

Hello,

I use superfish plugin on my website ( http://www.pms-clan.org ) for
the menu. The fade method for showing works ok (but it's sometime
"flickers", a little bit annoying but it's ok), but i can't make it
slide, using height or width method.

I use for example this to show up :

$(document).ready(function(){
      $("ul.sf-menu").superfish({
                     animate : {opacity: 'show', width: 'show' },
                     speed: 'slow',
                     autoArrows: true,
                     dropShadows: true
        });


Opacity will work, but not width, and it's the same for height.

Any help is welcome :)

Thanks a lot
Fab
