Often, when you display a list of pages, you want to dictate which ones show up
first and which ones are last. You can do this by typing in a number for the Order
setting, which appears in the Page Attributes box when you create (or edit) a page.
The Order setting affects the order of your pages in two situations: when you display
pages in an automatic menu and when you display them in the Pages widget with
the “Sort by” box set to “Page order.”
Ordinarily, WordPress sets the order number of every page to 0. Technically, that
means that each page is tied for first position, and the page order setting has no
effect. But if you want to set the order (say you want “Our Story” followed by “Our
Location” followed by “Contact Us”), you’d assign these pages steadily increasing
page-order numbers (say, 0, 1, and 2). The actual numbers don’t really matter—the
important thing is how they compare. WordPress always displays larger-numbered
pages toward the bottom of the list or on the right end of a horizontal menu, with
smaller-numbered pages closer to the top of a list or to the left of a menu bar. If two
or more pages have the same order value, WordPress orders them alphabetically.
TIP If you rearrange a bunch of pages, you need to change their page-order values. The easiest way to do
that is to go to the Pages list (choose Pages→All Pages), point to a post, and click the Quick Edit link. This way,
you can quickly modify some page information, including the order, without opening the whole page for editing.
There’s another way to group pages: You can designate some as child pages that
belong to a specific parent page. (You may have used this type of organization
before, to create subcategories for your posts.) To create
this hierarchy, you set the Parent setting in the Pages Attribute box when you
create or edit the page.
The order settings create the nicely styled menu and nested list .
The menu displays subsidiary pages in submenus, while the Pages widget slightly
indents nested pages.
Life can get a bit confusing when you order and group pages. Just remember that
when WordPress orders pages, it compares only the pages at the same level. For
example, you can use the page order to adjust the position of the Assault Charges,
Drug Offenses, Family Law, and Personal Injury Defense pages with respect to one
another. However, WordPress won’t compare the order values of the Family Law
and Legal Disclaimers pages, because they aren’t at the same level and won’t ever
be shown next to each other.
