Note: you must first create a page and then you can add it to the menu

• Click APPEARANCE > MENUS
• At the top of the center column, choose the correct menu and click SELECT
• Within the box titled PAGES, select the page you wish to add to the navigation under the MOST RECENT TAB (or “All Pages” tab)
• Click ADD TO MENU and drag the page, which now appears at the bottom on the menu, under the parent page you wish for it to appear below
• Drag the page slightly to the right to indent it under its “parent” page. This makes it a “dropdown” menu item instead of a “main” menu item
• Click blue button in the upper right corner
