I’d like to share this tip since it took me a while to figure it out and yet master it. Here’s how you change the direction of the top menu on a magento site:
edit the file: skin/frontend/default/YOUR THEME/css/menu.css. and look for the word “left”, substitute it with the word “right”. After each change, refresh your browser page to see the effect of your action on the page before moving on to the next instance of the word “left”.
You can also change all the other parts of the website to rtl by checking the class or id for each element and changing “left” to “right” in the css file where the class or id is defined.
Wishing you all the best with rtl interfaces on Magento.
Plz don\’t hesitate to post any questions regarding this issue.
