I got the code from here and the related files from here. I just changed the paths and kept only one menubar, its not working for me. Here is what I can see:

Here is my code:
In the HTML Head:

<script src="Rules/navbar/jquery.ui.menubar.js"></script>
<script>
$(function() {
function select(event, ui) {
$("<div/>").text("Selected: " + ui.item.text()).appendTo("#log");
if (ui.item.text() == 'Quit') {
$(this).menubar('destroy');
}
}
$("#bar1").menubar({
position: {
within: $("#demo-frame").add(window).first()
},
select: select
});
$(".menubar-icons").menubar({
autoExpand: true,
menuIcon: true,
buttons: true,
position: {
within: $("#demo-frame").add(window).first()
},
select: select
});
$("#bar3").menubar({
position: {
within: $("#demo-frame").add(window).first()
},
select: select,
items: ".menubarItem",
menuElement: ".menuElement"
});
});
</script>
<style>
#bar1, #bar2 { margin: 0 0 4em; }
</style>
