Previewing your form as you go along
As you are building up your form, or when you have completed the form, you can get a sense of what it will look like on a mobile device by clicking 'Android' or 'iPhone' on the 'Preview' line at the top of the green Form section of the form builder. As an example below is a preview of the above form on an Android device.
NOTE: 'Select One' options will appear as drop-down lists when loaded on the phone, however, for preview purposes you will see them as a list of options. Also, on an Android device, if your form contains more than five form elements, the form will automatically be paginated into a series of pages to make it easier to enter large amounts of data.
