The widget is to introduce your guests into the reservation process with fewer fields. It can contain the calendar and/or a form. The widgets form field’s works like in the normal form, but it’s used to pre fill the values of a normal form. The whole reservations process can’t be made through it, so you need to define the URL of a page or post with a form in it. If you enter resource instead it’ll post the information’s to the selected resources page.
