Creating a Click-action CSS3 Dropdown Menu with jQuery

· Web Dev Zone

Learn why developers are gravitating towards Node and its ability to retain and leverage the skills of JavaScript developers and the ability to deliver projects faster than other languages can.  Brought to you in partnership with IBM.

Nowadays, pure CSS3 menus are still very popular. Mostly – these are UL-LI based menus. Today we will continue making nice menus for you. This will be a nice dropdown menu (looks like menu at http://www.microsoft.com/) with onclicking (instead onhover).


Here are the final results (what we will creating):

Ok, download the example files and lets start coding!


Step 1. HTML + JS

As usual, we start with the HTML.

Here is the full html code for our menu. As you can see – this is a multi level menu. I hope that you can easily understand it. The whole menu built on UL-LI elements.

<link rel="stylesheet" href="css/style.css" type="text/css" media="screen">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

<div class="example">
    <div class="menu">
        <span>
            <ul id="nav">
                <li><a href="#">Home</a></li>
                <li><a href="#">Tutorials</a>
                    <div class="subs">
                        <div>
                            <ul>
                                <li><h3>Submenu #1</h3>
                                    <ul>
                                        <li><a href="#">Link 1</a></li>
                                        <li><a href="#">Link 2</a></li>
                                        <li><a href="#">Link 3</a></li>
                                        <li><a href="#">Link 4</a></li>
                                        <li><a href="#">Link 5</a></li>
                                    </ul>
                                </li>
                                <li><h3>Submenu #2</h3>

                                        <li><a href="#">Link 8</a></li>
                                    </ul>
                                </li>

                                    </ul>
                                </li>
                                <li><h3>Submenu #8</h3>
                                    <ul>

                                        <li><a href="#">Link 19</a></li>
                                    </ul>
                                </li>
                            </ul>
                        </div>
                    </div>
                </li>
                <li><a href="http://www.script-tutorials.com/about/">About</a></li>
                <li><a href="http://www.script-tutorials.com/click-action-css3-dropdown-menu-with-jquery/">Go Back To The Tutorial</a></li>
            </ul>
        </span>
    </div>
</div>

<script type="text/javascript">
jQuery(window).load(function() {

    $("#nav > li > a").click(function () { // binding onclick
        if ($(this).parent().hasClass('selected')) {
            $("#nav .selected div div").slideUp(100); // hiding popups
            $("#nav .selected").removeClass("selected");
        } else {
            $("#nav .selected div div").slideUp(100); // hiding popups
            $("#nav .selected").removeClass("selected");

            if ($(this).next(".subs").length) {
                $(this).parent().addClass("selected"); // display popup
                $(this).next(".subs").children().slideDown(200);
            }
        }
    }); 

});
</script>

In the bottom – we can see the extra jQuery code. Here are the onclick events and a little bit of animation.

Step 2. CSS

Here are the CSS styles. The first two selectors make the layout of our demo page. All the rest belong to the menu.

css/style.css

/* demo page styles */
body {
    background:#eee;
    margin:0;
    padding:0;
    font-family:Segoe UI,Tahoma,Arial,Verdana,sans-serif;
}
.example {
    background:#fff url(../images/blue.jpg);
    width:700px;
    height:500px;
    border:1px #000 solid;
    margin:20px auto;
    padding:15px;
    border-radius:3px;
    -moz-border-radius:3px;
    -webkit-border-radius:3px;
}

/* main menu styles */
.menu {
    background-color:#d0e6f5;
    text-align:center;
    width:100%;
}
.menu > span {
    display:inline-block;
    margin:0 auto;

#nav {

#nav > li.selected  > a {
    background-color:#FFFFFF;
    border-color:#999999 #999999 #FFFFFF;
    z-index:2;
}
#nav li div {
    position:relative;
}
#nav li div div {
    background-color:#FFFFFF;
    border:1px solid #999999;
    padding:12px 0;
    display:none;
    font-size:0.75em;
    margin:0;
    position:absolute;
    top:-1px;
    z-index:1;
    width:190px;
}
#nav li div div.wrp2 {
    width:380px;
}
#nav .sep {
    left:190px;
    border-left:1px solid #E3E3E3;
    bottom:0;
    height:auto;
    margin:15px 0;
    position:absolute;
    top:0;
    width:1px;
}
#nav li div ul {
    padding-left:10px;
    padding-right:10px;
    position:relative;
    width:170px;
    float:left;
    list-style-type:none;
}
#nav li div ul li {
    margin:0;
    padding:0;
}
#nav li div ul li h3 {
    border-bottom:1px solid #E3E3E3;
    color:#4F4F4F;
    font-weight:bold;
    margin:0 5px 4px;
    font-size:0.95em;
    padding-bottom:3px;
    padding-top:3px;
}
#nav li ul ul {
    padding:0 0 8px;
}
#nav li ul ul li {
    margin:0;
    padding:0;
}
#nav li ul ul li a {
    color:#0060A6;
    display:block;
    margin-bottom:1px;
    padding:3px 5px;
    text-decoration:none;
    font-size:0.9em;
}
#nav li ul ul li a:hover{
    background-color:#0060a6;
    color:#fff;
}
