Adding Pages to Menu
Basic pages and landing pages needed to be added to the navigation via menu settings.
You need to assign each page to a location on the site. To add it to the menu, check Provide a menu link. If this page goes into the main navigation at the top of the site, keep <Main menu> selected. If you want it underneath a main menu item, look at the Parent item drop- down options and choose the appropriate subpage to which you want to assign it.
Note: On older sites, the menu link option is below the body instead of to the right.

Using the Main Navigation
You can see the Menu Settings by going to Structure > Menus > Main navigation in the black bar. Here you will find every page that was assigned to a menu. You can rearrange the order of the Main menu and the children pages in this screen as well – just click and drag the arrows on the far left. Click Save to save any changes.
