Associative array of menu location identifiers (like a slug) and descriptive text.

Examples

#1 An example of registering multiple menus

It also automatically adds menu support to the theme.

add_action('after_setup_theme', function(){
	register_nav_menus( array(
		'header_menu' => 'Header menu',
		'footer_menu' => 'Footer menu'
	) );
});

We will display these menus with wp_nav_menu().

Notes

This function automatically adds menu support to the theme, so there's no need to call add_theme_support('menus') if you are using it.

In the menu settings of the theme, you can enable "Advanced Settings" that allow you to specify various attributes of the HTML links of the menu items.
