To add the multi-page feature to your form, look under Other Fields options in your Form Editor and select the field Page Break. Two new elements will be added to your form: the page break element and the pagination progress bar.
To add new page breaks, add the field again where the page should end. Each horizontal line is the beginning of a new page in your form.
To customize the multi-page form feature, click on each oh the pages you have created and the Edit Field panel will open on the left side of the page.
To remove a page break, hover with your mouse in between the pages in the main view. The Merge pages button will appear. Once clicked, the page is removed.
The result is the following: when users access your multi-page form, they will see the first section/page and the button Next at the bottom, that will take them forward. The navigation can also be done towards previous pages, using the link Previous.
