I want to be able to create a form and use it offline

Can this be done?

You can convert your form into a fillable PDF form so that you can use it in the tablet without internet connection. However, you need internet connection in order for it to be submitted.

Here are 2 helpful guides:

Hope that helps. Thank you.
