Is it possible to generate a pdf with the information filled up by the users right after they click submit?

the situation is like this: 

integrated jot form in wix >>> user fill up the info >> user click submit >> pdf generated with the selected options in the form/info filled up by the user specifically. 

Is this feature available in JotForm?

Do you want to send a PDF copy of the submission to the user/submitter? Unfortunately, generating a PDF by a click of the submit button is not possible. You can do it this way:

1. Create an autoresponder email, add the PDF download link in the email body or enable the PDF attachment in the settings. Of course, you need to add an email field in the form and use it as the recipient in the settings.

2. If you don't want to add an email, you can add the PDF Download Link in the Thank You Page:
