In this example, we will add the possibility to switch to German in the app. Check out the instruction below
The feature allows you to translate not only the app content but also text that is not user controlled, such as interaction, hints, selection, pagination, messages, and validation.
Navigate to the App triggers section in the right side panel and create a new action for the On App Load trigger.
Select the JavaScript Code type and specify the following code to initialize all the translations using i18n.init({...}):
The default interpolation in UI Bakery is { prefix: '{', suffix: '}' }. Therefore, you should use single curly braces to insert your values into the string.

For a Form, for example, you may also want to add translation for the Submit button. Simply add this field to the code above (e.g.: submit: 'Einreichen') and add {{i18n.t('submit')}} to the Submit button text's value in the Form settings.
Add a Select component to the working area and add the languages you need to the Options field, for example:
In the component's Value field, specify {{i18n.language}}.
Next, navigate to the Select component's Triggers section and create a new action for the On Change trigger.
Select the JavaScript Code step and specify the following code:
i18n.changeLanguage(data)
Finally, add translations anywhere you need to the text by using the i18n.t function.
In our example here, we've added translation to the Heading component:
{{i18n.t('welcome')}}
Done! Now when you select a different language in the Select component, your app will be translated automatically.
