In the past few years, we have covered a bunch of cool plugins that let you add interactive polls and trivia/personality quizzes to your site. Forminator gives you more control. It is a drag & drop form builder that you can use for contact forms, polls, and quizzes.
Forminator integrates with Google Sheets, AWeber, MailChimp, and other services. You can drag & drop name, email, phone, number, website, and other fields in a flash. The plugin is optimized for Gutenberg. It is GDPR ready.
Forminator is developer friendly, so you can come up with your own custom apps with it.
