Our editor and any default content provided with our design templates are only available in English. Through Text Element and any other tool to add content, you can do so in any language. 

If you are interested in creating a multilingual site, you could look into using a translation widget such as Bablic (https://www.bablic.com). With a translation widget, you would enter all your content on your website in one language and then use the widget to translate the website to another one.
