WPForms is a plugin for adding any kind of contact forms to your WordPress site. You can make your WPForms multilingual using WPML.
WPML offers two translation editors you can use for translating your site’s content:
WPML classic translation editor (CTE).
WPML advanced translation editor (ATE) offers automatic translation, a glossary, spell checker, and more!
Besides translating your site content yourself, you can also:
Send your content for translation to a professional translation service.
Create your own team of local translators from the Translation Roles tab in Translation Management and assign translation jobs to them.
