Hi everyone,

I obtain a code to create a collapsible sidebar for my website layout from here: http://www.depiction.net/?id=csssidebar

I have successfully implemented it but I would like to add cookies to it so that it can remember the state. I tried my best but due to my limited knowledge in programming, I could not figure out how to do it.

Would be grateful if anyone can assist:

Code:
<script type="text/javascript">
    <!--

    // begin function.
    function toggle() {

        // Initialize our object data from our XHTML divs.	
        var bar = document.getElementById('sidebar');
        var barText = document.getElementById('sbText');
        var box = document.getElementById('content');

        // If the sidebar is expanded...
        if (bar.style.width == '250px') {

            // Collapse it by setting its width to 15px
            bar.style.width = '15px';

            // Hide the sbText div so that its text isn't visible or
            // repositioned.
            barText.style.display = 'none';

            // Resize the content div to its new, expanded width.
            box.style.width = '720px';

        // Otherwise, if the sidebar is already collapsed...
        } else {


            // Restore the width of the sidebar.
            bar.style.width = '250px';

            // Make the sbText div visible again.
            barText.style.display = 'block';

            // Set the content div width back to original size.
            box.style.width = '500px';
        }
    }

    // -->
</script>
Thanks in advance!
