Add a language switching control

1. First, back up your page layout in the backend so you can restore it if an error occurs.

In the left navigation pane of the backend, go to my site > backup and restore and click Back up Current Version.

2. In the left navigation pane of the backend, find the website language settings and enable the languages you need. 

3. On the design page, you can switch to a specific language to edit that version of the page.

Click the language button in the top toolbar (the default is Simplified Chinese) to expand the drop-down panel, which provides the following options: Simplified Chinese (Recommended), English, Japanese, Korean, and German.

4. By default, your domain name directs visitors to the primary language version of your site. To allow them to switch languages, you must add a language switching control to each language-specific page.

In the designer, open the column navigation panel from the menu on the left. At the bottom of the panel, locate the language switching area (which displays the current language, for example, "Simplified"). Click the blue Select button to add the control.
