We are working through this approach for translations, https://blog.teknkl.com/smoothing-embedded-marketo-form-loads/ . Three questions came up today that I was wondering if you could shed some light on.
How do you manage/translate the "This field is required" message and other validation error messages?
How do you handle the translation of drop downs, checkboxes (multi-selects)?
Related to question 2, is it possible for us to translate the stored values or is this method just for front end translations?
That's the ValidationMessage property of the field in the descriptor.
Similarly, those will be in the PicklistValues property.
You can translate just the value or the label, too. All up to you.
