When opening a form, you can see on the status/progress bar at the bottom of the screen how many pages it has. The active page is colored purple. The form illustrated here has two pages to start with.
Depending on rules set for the form elements, the progress bar will dynamically show additional pages. One page may for instance be set to hidden, unless a specific option is chosen. The page will then only show up in the progress bar when the option is selected.
The progress bar also shows if mandatory questions are completed, or if there are questions with warnings (an exclamation mark) or serious errors (a road sign with an exclamation mark).
