Why some forms are one page form and other are multi-page form?

I have several form drafts ready, but I found some of the form are one-page form, some has to click "next step" to go next page.

I don't know when and how I set this? 

Please let me know...

I did check your last edited form and found that it is using new form layout which will display one question per page. If you want to display all questions together or multiple question in one page, you need to switch your form to legacy layout.

Please confirm if you want to switch your form to old legacy layout and we will create a ticket and forward it to our backend team. 

We will wait for your response.

I have moved your second question to a new thread so that we can address it separately. You will be answered in the following thread:  https://www.jotform.com/answers/1279804

Dear Ashwin,

Thank you for your reply, I want to keep the new form layout, I am just wondering why it is different...So can you tell me can I switch/decide whether a form is new/old layout by myself? If yes, where can I set it?

Thanks.

P.S I will check another thread answer.

I'm sorry for the trouble caused to you. 

Did you clone this form from some other account? Can you please create a new form in your account and let us know if it is created in new or old layout?

If you want to change the form layout, you need to create a ticket and we will forward it to our backend team.

Hi

When I create a new form, it is old layout. I don't remember how I started the new layout form...it's okay I would like to keep the same. 

In future if I need a new layout form I will let you know.

Thanks.

Sure. Do get back to us if you would like your form to create in new layout and we will do the needful.
