JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
At the moment you cannot embed the form directly in Facebook's news-feed, you can however include it using the tab feature in your Facebook page.
You can then share a link to this tab on your news-feed/post.
Kindly refer to this guide on how to realize the integration of jotform to Facebook
