Q:

Sliding Panels with JavaScript

This example I've found is exactly what I was looking for:  http://jsfiddle.net/sg3s/RZpbK/ 
Thx to the author sg3s
jQuery(function($) {

    $('a.panel').click(function() {
        var $target = $($(this).attr('href')),
            $other = $target.siblings('.active'),
            animIn = function () {
                $target.addClass('active').show().css({
                    right: -($target.width())
                }).animate({
                    left: 0
                }, 500);
            };

        if (!$target.hasClass('active') && $other.length > 0) {
            $other.each(function(index, self) {
                var $this = $(this);
                $this.removeClass('active').animate({
                    left: -$this.width()
                }, 500, animIn);
            });
        } else if (!$target.hasClass('active')) {
            animIn();
        }
    });

});

But I got a little problem with it. I would like the panels to "open" and "close" from the right. I'm not familiar with javascript and I'm not able to tweak it properly.
Can anyone help me with this ?

A:

Just replace the left: -($target.width()) with left: $target.width() in both places
