How to add another menu in WordPress

First, add the following code in your functions.php file to register a new menu. In this example we call it “Secondary Menu.”

functions.php:

function register_secondary_menu() {
	register_nav_menu( 'secondary', __( 'Secondary Menu', 'This is the secondary menu' ) );
}
add_action( 'after_setup_theme', 'register_secondary_menu' );

In the admin dashboard, go to Appearance -> Menus. Click on the link, “create a new menu,” as shown below.

After you finish creating your menu structure, you will see a new option at the bottom under “Theme locations.” Select the menu that you registered. (In this example we registered a menu called “Secondary Menu”.)

Now add the following code in the template file (header.php, footer.php, etc.) where you want the menu to appear.

wp_nav_menu( array( 'theme_location' => 'secondary', 'menu_id' => 'secondary-menu' ) );
