Multiquestion feature

Can I have a multi-question feature on the all questions on one form sheet? And could I disable the submit button feature on the single question forms, when I disable the submit button on https://form.jotform.com/91544599276169   it doesnt work.

I'm afraid that multi-line question is exclusive for cards layout form (single question per page).

Regarding the submit button, I tested your form but I wasn't able to replicate any problem. Submit button is properly disabled when a condition is met (you cannot submit).

Let us know if you have any further issues.

Thank you!

Is there a way I a can have it disappear?

Unfortunately, it is not possible to hide the submit button in the card form layout. You can only disable it, but you can't hide it. That feature is only available in the classic layout form.
