Searching Plugin for hiding parts of the content with a form

Hello,

I would like to hide certain parts of my editor content. Instead there should be shown a form where you have to insert some marketing-data like name, mail, preferences…

On sucessfully filling in the form and sending, the form should dissapear and reveal the hidden content.

Is there any solution or plugin which can hide certain parts of content and showing a form instead?

Thank you and greetings, Chris
