Add a language switcher to a subdomain site

Add a container div and one script tag before the closing body tag to show a dropdown of flags on a subdomain site.

Updated February 20, 2026

The language switcher for a subdomain site is a dropdown of flags. You add two pieces of code to your pages: a container where the dropdown shows, and a script that loads the widget.

Add the switcher

Add this code to the place you want the dropdown of flags to show:
html
```
<div id="fluentc-lang-switcher"></div>
```

Just before the closing </body> tag, add:

html

<script async
   src="https://widget.fluentc.io/fluentc.v1.0.1.js"
   integrity="sha384-i67c0HA8k9cveXN7Zmg4glsraDLNYO62f0DK2H/Cu7fNbulBhhDJz0ZzAT05p8m6"
   crossorigin="anonymous"></script>

Note: The script loads the widget from https://widget.fluentc.io/fluentc.v1.0.1.js. Copy the tag exactly as shown, including the integrity and crossorigin attributes.

Add the switcher

Start with one language.
