I don't think that you can. However, you can use individual text boxes and make your links that way.
BTW, I believe that the menu bar is a javascript function. SE's cannot see links installed using js.
I do use js menus but I also reproduce the links using text as a footer on pages where I consider SEO important.
The top menu on this page
www.zone5pix.com is js. I then have a text menu for the SE's on the bottom of the page.
