In the Integration module of Spotler Activate Search, you might see Site integration v1 and Site integration v2 below eachother. This means that you get to test and use the new v2 template functionalities and eventually switch to v2 completely. The v2 template offers more integration options and can be fully customizable, while having faster responsive times. New features will also be developed on v2.
Not sure which version of Site integration and templating you're using? Ask the admin of your account on how this is set up for you.
Are you just seeing Site integration, without the v1 and v2? This means that you are working with a v2 template only. The admin of an account is able to toggle this on or off.
Languages
The Search interface can be used in most common languages, and you can easily add translations.
Activate the languages for your v1 template that you want to use by enabling them with the toggle. Enabled languages can then be used for translating filter names, sort options, and interface texts under the section Translations in the Integration module. The default language can not be switched off, this one is set via User Experience in the Integration module.
Languages in Site Integration are only available for some versions of Spotler Activate Search. If you don't see this in your account, contact support if you want to know more about this.
