You will create a form in another language the same way you will create a form. The only difference is while editing the form fields, the form field labels should be written in the language of your choice. For example, for creating a form using French, labeling a field with Name on a normal form will become ‘Nom’.
After creating the form, you can change the text of the submit button on the form’s customise page to the translation of Submit in the language you created your form with. For example, the Submit button text for a French form can be changed to Soumettre.
For right-to-left languages forms, you can also change the layout of your form to a right-to-left layout.
