Create Sub-Pages or Sub-Menus
Sometimes you may want to create sub-pages. You may want to group items
together under a more general category. For instance, if you have a tee shirts
page and you would like to split them apart into children's ladies, and men's tee
shirts.
By enabling the “Change Main Page to Sub Page & Vice Versa" you can move the
pages up or down and click the right arrow. The page name will indent to the right
indicating it is a sub-page – categorize the pages as either Main menu or
Sub menu.
