How does the banner detect languages?

Updated October 19, 2021 05:54

The cookie banner by default uses the browser language of the visitor. This behaviour can be overridden by using data attributes.

How does the banner determine which language to show? There is an order to how it's decided to show which language:

if language switcher is enabled, use the language remembered from previous user choice in the switcher
if client added language attribute to banner, and set it to inherit , use the language defined on <html> element
if client added language attribute data-language="fr" to banner and set it to a language, use that language
detect browser language and try to use that
use the fallback language (first on in the list in our portal) if none of the above managed to determine a language for the banner
