Step1. HTML
First create an unordered list for your base top navigation. Then simply nest another unordered list for your sub navigation.- <ul class="topnav">
- <li><a href="#">Home</a></li>
- <li>
- <a href="#">Tutorials</a>
- <ul class="subnav">
- <li><a href="#">Sub Nav Link</a></li>
- <li><a href="#">Sub Nav Link</a></li>
- </ul>
- </li>
- <li>
- <a href="#">Resources</a>
- <ul class="subnav">
- <li><a href="#">Sub Nav Link</a></li>
- <li><a href="#">Sub Nav Link</a></li>
- </ul>
- </li>
- <li><a href="#">About Us</a></li>
- <li><a href="#">Advertise</a></li>
- <li><a href="#">Submit</a></li>
- <li><a href="#">Contact Us</a></li>
- </ul>
Step2. CSS
Next, it’s time to style the navigation wireframe with CSS.- ul.topnav {
- list-style: none;
- padding: 0 20px;
- margin: 0;
- float: left;
- width: 920px;
- background: #222;
- font-size: 1.2em;
- background: url(topnav_bg.gif) repeat-x;
- }
- ul.topnav li {
- float: left;
- margin: 0;
- padding: 0 15px 0 0;
- position: relative; /*--Declare X and Y axis base for sub navigation--*/
- }
- ul.topnav li a{
- padding: 10px 5px;
- color: #fff;
- display: block;
- text-decoration: none;
- float: left;
- }
- ul.topnav li a:hover{
- background: url(topnav_hover.gif) no-repeat center top;
- }
- ul.topnav li span { /*--Drop down trigger styles--*/
- width: 17px;
- height: 35px;
- float: left;
- background: url(subnav_btn.gif) no-repeat center top;
- }
- ul.topnav li span.subhover {background-position: center bottombottom; cursor: pointer;} /*--Hover effect for trigger--*/
- ul.topnav li ul.subnav {
- list-style: none;
- position: absolute; /*--Important - Keeps subnav from affecting main navigation flow--*/
- left: 0; top: 35px;
- background: #333;
- margin: 0; padding: 0;
- display: none;
- float: left;
- width: 170px;
- border: 1px solid #111;
- }
- ul.topnav li ul.subnav li{
- margin: 0; padding: 0;
- border-top: 1px solid #252525; /*--Create bevel effect--*/
- border-bottom: 1px solid #444; /*--Create bevel effect--*/
- clear: both;
- width: 170px;
- }
- html ul.topnav li ul.subnav li a {
- float: left;
- width: 145px;
- background: #333 url(dropdown_linkbg.gif) no-repeat 10px center;
- padding-left: 20px;
- }
- html ul.topnav li ul.subnav li a:hover { /*--Hover effect for subnav links--*/
- background: #222 url(dropdown_linkbg.gif) no-repeat 10px center;
- }
Step3. jQuery
For those who are new to jQuery, you can learn about it here.The following script contains comments explaining which jQuery actions are being performed.
- $(document).ready(function(){
- $("ul.subnav").parent().append("<span></span>"); //Only shows drop down trigger when js is enabled (Adds empty span tag after ul.subnav*)
- $("ul.topnav li span").click(function() { //When trigger is clicked...
- //Following events are applied to the subnav itself (moving subnav up and down)
- $(this).parent().find("ul.subnav").slideDown('fast').show(); //Drop down the subnav on click
- $(this).parent().hover(function() {
- }, function(){
- $(this).parent().find("ul.subnav").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
- });
- //Following events are applied to the trigger (Hover events for the trigger)
- }).hover(function() {
- $(this).addClass("subhover"); //On hover over, add class "subhover"
- }, function(){ //On Hover Out
- $(this).removeClass("subhover"); //On hover out, remove class "subhover"
- });
- });
