jQuery CSS3 a Mega Drop-Down Menu

Mega drop-down menus are not actually new, but more and more we see them on popular websites and blogs. With the ever increasing quantity of content on the web we have to figure out solutions to display content and navigation but still keep everything usable and provide a good user experience. It’s no wonder mega drop-downs are now used more often.

we’ll take a look at creating a simple HTML site with a horizontal navigation bar where a menu item will have a mega drop-down attached to it. I used jQuery for the drop-down and some CSS3 for the rounded corners.

 

Step 1 – The Markup

Before we can start working on the mega drop-down menu we will need a working site so let’s write our HTML. Of course for the purpose of this tutorial the links in the menu won’t work.

Let’s start with the header. We’ll include our style.css file and the jQuery library

Mega Drop-Down Menu Demo


Then we will add a H1 and a paragraph that explains what the demo site is about:

Mega Drop-Down Menu Demo Site

This page is an example of a mega drop-down menu, but with more options than the usual suckerfish drop downs. We used jQuery, CSS3 and HTML to create this mega drop down menu.

And then our navigation bar (without the drop-down for now):

We have 6 menu items and we will use the ‘services’ tab and attach our drop-down to it. But before we do that let’s add some content to our site. We’ll put 2 paragraphs with some Lorem Ipsum inside a div.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut eget eros libero. Fusce tempus quam sit amet erat mollis a fermentum nibh imperdiet. Fusce iaculis sapien in turpis aliquet porta. Donec tincidunt gravida tortor, vel dignissim augue convallis sit amet. Aliquam auctor ornare accumsan. Cras convallis elit tincidunt arcu semper egestas. Mauris interdum fringilla nisi. Cras a dapibus lectus. Praesent blandit ullamcorper ornare. Nam hendrerit sollicitudin urna non ultricies. Phasellus condimentum auctor risus, at accumsan tellus tempor vel. Nunc mattis eleifend dolor at adipiscing.

Ut purus metus, fermentum vitae pulvinar vel, elementum eget nulla. Pellentesque posuere, enim ut dapibus vestibulum, leo nunc porttitor neque, sed pulvinar orci sem eleifend sapien. Nullam at odio nibh, eu pharetra ipsum. Pellentesque eget ante nec ante consequat ullamcorper a vitae mauris. Integer lacus lorem, sollicitudin vulputate posuere at, commodo a sapien. Vivamus lobortis vehicula imperdiet. Donec a congue tortor. Fusce augue tortor, pretium pharetra pellentesque ornare, laoreet nec sapien. Ut eget magna tellus. Pellentesque posuere accumsan condimentum.

And then we can end our document with the closing body and html tags.

Before we dive into the CSS, let’s add our drop-down. Here’s the new markup for the menu. I added a class to the ‘services’ list item since this is the one that will have the mega drop-down and I added a div with some content in it.

As you can see the whole mega drop-down panel is contained within the div=”servicesdropped”. I put a paragraph and some unordered lists in there (later styled using CSS)

Part 2 – jQuery

Now let’s work on the jQuery part. It’s actually very simple. I want the ‘services’ tab to open up a mega drop-down panel when clicked. And I want the panel to close the ‘services’ tab is clicked again.

Let’s insert this code in the head of our document:


$(document).ready(function(){
$(".downservices").click(function(){
$(".servicesdropped").toggle("fast");
});
});

This will tell the browser to toggle the panel with a class of .servicesdropped up and down when the list item with a class of .downservices is clicked. Simple huh?

Step 3 – CSS3

I used some CSS3 to give our divs and paragraphs some rounded corners. Of course the rest of the CSS file is pretty straight forward

body {

}

.servicesdropped {
display:none;
text-align:left;

font-size:12px;

-moz-border-radius:5px;
-webkit-border-radius:5px;
border:1px solid #000;
margin:10px 0 0 20px;
padding:10px 20px 20px;
}

.servicesdropped p.textleft {
float:left;
font-size:12px;
width:200px;
margin:10px 0 0;
padding:0 20px 15px 10px;
}

.servicesdropped ul.middle {
text-align:left;
float:left;
border-right:1px solid #333;
border-left:1px solid #333;
font-size:12px;
width:180px;
margin:0;
padding:0;
}

.servicesdropped ul.right {
text-align:left;
float:left;
font-size:12px;
width:178px;
margin:0;
padding:0;
}

.servicesdropped ul.right li a,.servicesdropped ul.middle li a {
list-style-type:none;
display:block;
color:#888;
font-size:12px;
margin:0;
padding:5px 0 5px 20px;
}

.servicesdropped ul.right li a:hover,.servicesdropped ul.middle li a:hover {
list-style-type:none;
color:#9FC54E;
display:block;
font-size:12px;
margin:0;
padding:5px 0 5px 21px;
}

Our rounded corners are styled using the border-radius property (the W3C validator doesn’t like this, but it looks good and doesn’t impact usability at all). Something like this:

border:1px solid #000;
-moz-border-radius:5px;
-webkit-border-radius:5px;

Of course I changed the border color to match the color of my divs and paragraphs. The rounded corners won’t work in IE6
