How can I make a horizontal nav menu that on hover reveals the sub menu items and slides up above the main nav using jquery?

Question

I want it to slide up from the bottom right about my main nav menu just like this site. jefflewisdesign.com I know that site is down in flash but I know that nav can be done in jquery. thanks.

Here is how I have it so far.

 <div id="slidebottom" class="slide">

    <h2>Item</h2>

    <div class="inner"></div>

  </div>

$(document).ready(function() {

        $(".inner").hide();


    $('h2').hover(function() {

      $(this).next().slideToggle();

    });

  });
