Is it possible to hide the “send” button and make it visible only when you finish answering the form?

@Sebas-Celade, this is not possible. However, you could overcome this by setting the survey questions as mandatory when designing the form, as outlined in our previous post:

So with a mandatory question/s, the enumerator can only submit the form to the server once all the questions are filled up. If anything is missing, the form/submission would not be submitted to the server.
