Toggle Ordered/ Unordered List Using jQuery


So let us say you have a tree like structure created with a bunch of <ul> and <li>. Now you come across a requirement where you need to expand and collapse these sections. Let us see how to do this using jQuery (tested on IE and Firefox)


<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>    

    <style type="text/css">

        .clsUL

        {            

            cursor:hand;

        }

    </style>

    <script src="Scripts/jquery-1.2.6.js" type="text/javascript">

    </script>

 

    <script type="text/javascript"> 

        $(document).ready(function(){

        $('#unord li').click(function() { 

                    $(this).children('ul').slideToggle("slow"); 

            }); 

        });

    </script>

 

</head>

 

<body>

    <form id="form1" runat="server">

    <div>

    <ul id="unord" class="clsUL"> 

        <li>Client-Side Languages

            <ul>

                <li>

                    jQuery

                </li>

                <li>

                    JavaScript

                </li>

                <li>

                    JScript

                </li>

            </ul>

        </li>

        <li>Server-Side Languages

            <ul>

                <li>

                    C#

                </li>

                <li>

                    VB.NET

                </li>

                <li>

                    Others

                </li>

            </ul>

        </li>

    </ul>   

    </div>

    </form>

</body>

</html>



The code shown above, collapses and expands the section of <li> kept inside <ul>. Needless to say, jQuery rocks!
