Using jQuery to Create a Drop-down Menu

dropdown Creating a drop-down navigation menu using jQuery and CSS is simple. Start off with some html for a basic navigation menu. This menu only has two links, the second of which is going to have a drop-down menu. [html] <div id="menu"> <ul> <li><a href="#">Link One</a></li> <li><a href="#">Link Two</a> <ul class="dropdown-menu"> <li><a href="#">Dropdown Link</a></li> <li><a href="#">Another Dropdown Link</a></li> </ul> </li> </ul> </div> [/html] Make sure you insert that second <ul> inside of the <li> tags of the drop-down menu's parent link. In the CSS, set a display: none on your drop-down menu so that it doesn't appear upon the initial page load. [css] #menu a{ text-decoration: none; color: #333; font-family: sans-serif; padding: 5px; } #menu ul li{ display: inline; } .dropdown-menu{ display: none; } [/css] All that's left to do is write a few lines of jQuery that allow for the drop-down menu to slideDown when the parent link is hovered upon (I've also added a line of code to make the drop-down menu smoothly slide back up when the user is done hovering). It should look something like this: [javascript] $(document).ready(function(){ $("#menu li").hover(function(){ $(".dropdown-menu", this).slideDown(100); }, function(){ $(".dropdown-menu", this).stop().slideUp(100); }); }) [/javascript] The .slideUp and .slideDown parameters determine how long the sliding animation lasts, so be sure to customize these to your liking. This code will accommodate as many navigation links and drop-down menus as you need, just don't forget to give every drop-down menu <ul> the same class that you used to call that first drop-down menu in the jQuery code.
