I've received a request asking to add RTL support to a jQuery slider plugin called Lof JSliderNews Plugin . Adding the RTL support was so simple and easy. Here's how it went:

To change the language of a WordPress site, just update the WPLANG constant in your wp-config.php file:
{syntaxhighlighter brush:php}
define ('WPLANG', 'ar'); //changes the language of the site to Arabic
{/syntaxhighlighter}

 jCarousel is a beautiful jQuery plugin. Personally it's one of my favorites! You can set up your caoursel up and running in just one line or two. Even theming it is easy. According to the project's page:

jCarousel is a jQuery plugin for controlling a list of items in horizontal or vertical order. The items, which can be static HTML content or loaded with (or without) AJAX, can be scrolled back and forth (with or without animation).

The only thing missing in this wonderful plugin is the RTL support. And in this tutorial, it won't miss it anymore.

Thank you Rami for the suggestion.

Superfish is a very famous jQuery plugin that allows you to add eye-catching effects to dropdown menus (<ul>). It works perfectly in major browsers (including IE6 with some style limitations) too. Well in RTL..it's just not there..so we're going to RTL this one.
