How can we add language options here?…

Hello,

Thank you for contacting us and for using XStore.

If you want to use your site in multiple languages, then you have to use WPML (paid) or Polylang plugin (free) as per your requirements: https://www.8theme.com/documentation/xstore/theme-translation/
Or read this article – https://colorlib.com/wp/wordpress-multilingual-plugins/

Please note that the language switcher menu shown in our demo is for illustrative purposes only. It demonstrates how the language selection menu may appear once a multilingual plugin is installed and properly configured. After choosing and installing the appropriate plugin according to its documentation, you will be able to add a language switcher to your website.

We hope this information is helpful. Should you require any further assistance, please do not hesitate to reach out. We are here to help you.

Best Regards,
8Theme’s Team
