Add Pages to Menu

To add pages to your menu go to Appearance -> Menus and check the proper boxes for the pages you want to add, and then click Add to Menu(Administrators Only.)

Arrange the menu items by clicking and dragging them. If a page is set as a child page (or sub-page), you can drag the navigation  items underneath and slightly to the right. This will make it display correctly as a child page.

When you are satisfied with your menu arrangement, click Save Menu.
