This is a new nice CSS3 menu with interesting behavior, where  use css3 transition and animation. This is UL-LI-based multilevel menu.

Step 1. HTML

As usual, we start with the HTML. Here are full html code of our menu. As you can see – this is multilevel menu built on UL-LI elements. But, it is a little unusual. I don’t wrap submenus into own UL element, I am going to hide them, and display if necessary.

index.html

<!DOCTYPE html>
<html lang="en" >
    <head>
        <meta charset="utf-8" />
        <title>CSS3 multilevel menu with transition and animation | Script Tutorials</title>

        <link href="css/layout.css" type="text/css" rel="stylesheet">
        <link href="css/menu.css" type="text/css" rel="stylesheet">
    </head>
    <body>

        <header>
            <h2>CSS3 multilevel menu with transition and animation</h2>
            <a href="#" class="stuts">Back to original tutorial on <span>Script Tutorials</span></a>
        </header>

        <div class="container">

            <ul id="nav">
                <li>
                    <a href="#">Parent link #1</a>
                    <a href="#">Sub #11</a>
                    <a href="#">Sub #12</a>
                    <a href="#">Sub #13</a>
                    <a href="#">Sub #14</a>
                </li>
                <li>
                    <a href="#">Parent link #2</a>
                    <a href="#">Sub #21</a>
                    <a href="#">Sub #22</a>
                    <a href="#">Sub #23</a>
                    <a href="#">Sub #24</a>
                </li>
                <li>
                    <a href="#">Parent link #3</a>
                    <a href="#">Sub #31</a>
                    <a href="#">Sub #32</a>
                    <a href="#">Sub #33</a>
                    <a href="#">Sub #34</a>
                </li>
                <li>
                    <a href="#">Parent link #4</a>
                    <a href="#">Sub #41</a>
                    <a href="#">Sub #42</a>
                    <a href="#">Sub #43</a>
                    <a href="#">Sub #44</a>
                </li>
            </ul>

        </div>

    </body>
</html>

Step 2. CSS

Here are the CSS styles of our menu. Maybe you’ve noticed – that in our html – I have two CSS files: layout.css and menu.css. The first file (layout.css) contain the styles of our test page. We will not publish these styles in this article, but if you wish – you can find these styles in our package.

css/menu.css

ul#nav {
    border: 1px solid #454545;
    display: block;
    height: 400px;
    margin: 0;

    width: 160px;

    -moz-border-radius: 9px;
    -ms-border-radius: 9px;

    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#f1f7ff', endColorstr='#d9e1ec')";
