Edit site on zoho sites

I need a developer to edit Navbar in Zoho sites to change links from English (EN) TO Arabic

(AR)

for example, switching from AR to EN by clicking on EN it will turn to AR and the URL goes from www.xx.com/index to www.xx.com/AR/index and so on for all pages

also, I want items in Navbar to appear in English if the user chose to view the page in English

and if the user chooses to view it in Arabic item will appear in Arabic
