How can i choose lang with click one button

Hi

I made links for change lang when the user clicked flag the lang has to change.

How Can I reach this ?

Hello,
did you already make them or do you want to do it?
If you already made it, how (in big line, I don't need the code) did you do it?
If you still did not make, do you use a SEO Links Language Prefix (yourwebsite.com/en/...) or not?
There is a language dropdown post: https://www.litecart.net/en/forums/12/templates-and-css/13928/drop-down-menu-to-change-language
Let me know if did it help you.
Bye.

it worked, thanks
