Rotate li items with jquery

I have a UL list like:

<ul>
  <li>menu1</li>
  <li>menu2</li>
  <li>menu3</li>
  <li>menu4</li>
  <li>menu5</li>
</ul>

I want to use this list as a animated JQuery menu. Setup in such a way that if a user clicks menu3 it becomes the first item in the list as menu1 and menu2 get appended to the end.

So after clicking on menu3 the ul would look like this:

<ul>
  <li>menu3</li>
  <li>menu4</li>
  <li>menu5开发者_如何学编程</li>
  <li>menu1</li>
  <li>menu2</li>
</ul>

Any guidance or suggestions would be greatly appreciated.

You could do something like this:

$("li").click(function() {
    var prev = $(this).prevAll();
    $.unique(prev).slideUp(function() {
        $(this).appendTo(this.parentNode).slideDown();
    });
});​​​

Give it a try here, the $.unique() call is because the elements from .prevAll() are in reverse order...and for appending to the end, we want them in document order.
