Special Drop-Down Menu

I am trying to achieve a simple drop-down menu with the following HTML structure. This structure is mandatory (I think) as explained in the illustrations below.

<nav role="navigation">
    <ul id="main-menu" class="nav top-nav clearfix">
        <li id="menu-item-1" class="menu-item"><a href="#">Menu 1</a></li>
        <li id="menu-item-2" class="menu-item"><a href="#">Menu 2</a></li>
        <li id="menu-item-3" class="menu-item"><a href="#">Menu 3</a></li>
    </ul>
    <ul id="sub-menu-1" class="sub-menu nav clearfix">
        <li class="menu-item"><a href="#">Sub Menu 1.1</a></li>
        <li class="menu-item"><a href="#">Sub Menu 1.2</a></li>
        <li class="menu-item"><a href="#">Sub Menu 1.3/a></li>
    </ul>
    <ul id="sub-menu-2" class="sub-menu nav clearfix">
        <li class="menu-item"><a href="#">Sub Menu 2.1</a></li>
        <li class="menu-item"><a href="#">Sub Menu 2.2</a></li>
        <li class="menu-item"><a href="#">Sub Menu 2.3/a></li>
    </ul>
</nav>

To get a better idea of what I am trying to achieve I've made the following illustrations:

  1. Simple menu with items arranged with inline blocks. As you can see, the menu scales to 100% of the container and has all the items arranged in center.

This is how the menu looks when the mouse is not hovering any menu item

  1. When hovering over a menu item which has a submenu. In the illustration that's Menu 1 which has Sub Menu 1 and it needs to display it on mouse hover, like a simple <ul><li><ul></ul></li></ul> would do. As you can see the submenu has to scale to 100% of the container and has all the items arranged in center.

When hovering over one item with a submenu

I think the best approach is with javascript (not sure you can do this with only CSS), but I am kind off stuck. The sub menu appears on main menu item hover, but as soon as I hover out into the sub menu in order to navigate, the sub menu disappears. Anyway, this is the javascript:

$('nav #main-menu .menu-item a').hover(
    function() {
        var id = $(this).parent().attr('id');
        id = id.substr(id.length - 1);
        submenu = $('#sub-menu-' + id);
        submenu.show();
    }, 
    function() {
        var id = $(this).parent().attr('id');
        id = id.substr(id.length - 1);
        submenu = $('#sub-menu-' + id);
        submenu.hide();
    }
);

I am pretty sure that there is a better way to do this.

I've also set up a FIDDLE for better understanding.

//show sub menu when we hover over an item
$('nav #main-menu > .menu-item')
 .on('mouseenter', function() {
    $('.sub-menu').hide();
    var id = $(this).attr('id');
    id = id.substr(id.length - 1);
    $('#sub-menu-' + id).show();
  });

//hide submenu when the mouse goes away
$('nav').on('mouseleave', function() { $('.sub-menu').hide(); });

Modified your fiddle here: http://jsfiddle.net/3z8MR/10/

Edit Add this line to conform to your specs in the comments

$('.sub-menu').on('mouseleave', function() { $(this).hide(); });
