Each menu template comes with preset page designs for a title page with headers, or subsequent pages without headers. Often times the title page has a more elaborate design background.
You can give any page either design option. Click the Format tab on the left hand side of the page, then select the Page option from the toolbar above the menu preview. Click one of the design options on the left hand side. The first option will have space allotted for headers at the top of the page, the second will not.
