I try to create a multilingual webflow page. I already have all the english contents but how can I design the page so that the viewer can change the language with one button? I have absolutely no clue how to approach this, I am grateful for any help 
Hi there!
If you set a multilingual website, once you change a language, it adds a parameter to the URL, for example, www.exampleshop.com?lang=en, or www.exampleshop.com?lang=fr. On the front page, you could set different flags, or provide a drop down, linking to different language URLs.
You may potentially auto direct your visitors to correct URLs based on their locations, for example, use Geo Targetly. With its Geo Redirect tool, you can detect your visitors’ location by IP and auto direct them to correct URLs displaying local languages, without one extra step having your visitors selecting their languages.
Hope it helps.
