What is JotForm?

At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
You can add a form to a Facebook page, but unfortunately it is not possible to add the form to a Facebook Group. As seen in this discussion on Facebook, Facebook does not support adding custom tabs to Facebook Groups.
An alternative would be to post the link of the form to your group and it pin it so everyone in the group will be able to see the link. You can get the link of the form by following this guide: Where to Find My Form URL?
I would like to inform you that forms are mobile responsive by default, so they can indeed be accessed on smartphones.
If you need further assistance, please let us know.
