Scenario: You’d like to add a page, post, or other item on your website to your top header navigation menu, or bottom footer navigation menu.
Solution:
Go to Appearance -> Menus, from this screen you’ll be given a list of items on your site, that you can check and click Add To Menu to add. You can select which menu to work on by using the Select Menu dropdown.
Once on your menu you can drop and drop to move it around, and even place items underneath other items to make a dropdown menu.
Once done editing your menu you can click Save Menu.
If you’re not able to find a piece of content, its group may be hidden, you can show or hide content groups by using the Screen Options in the top right.
