With the Language Selector part, you can allow website users to select language preferences for your website. Users select their preferences from the languages available on your website. You can make languages available in the Supported Languages section on the Settings tab in Sites & settings. The website renders text for selected languages based on the Language tabs of the parts on your website.
Tip: For the Language Support part to be effective, you must localize text on the Language tab before you use the part.
After users select languages, the website localizes text on the parts on your website. For example, if a user selects Spanish as the preferred language and goes to a donation form, the Donation Form part displays localized Spanish text from the Language tab. For more information about the Language tab and international pages for your website, see Add Localized Text For Web Pages.
Language preferences remain in place when users return to your website. For registered users, the program associates language preference with user logins. For anonymous users, the program associates language preferences with cookies on their machines.
