PRO2PDF is designed to map and merge Formidable’s web form data into an existing PDF Forms. So you would need to create a PDF form with all desired form fields, then map the web form to the PDF form.
Our other plugin, E2Pdf is capable of auto-creating the PDF form based on the web form. So it may be a better option for you. A fully functional version of E2Pdf is available for free on the WP Plugin Repository. The only limitation to the free version is to 1 ‘active’ one-page template.
