Add extra menu to theme

Question

What's the best way to add an extra menu location to a theme that already has one?

I want to add an extra menu in a child theme of a theme that currently has a single custom menu (what is the correct terminology here?!).

Do I just use register_nav_menu() to create an additional menu?

Answer 1

To answer my own question

Both register_nav_menu() and register_nav_menus() are additive, ie they add to the existing menu set (as long as you use a different location identifier). You don't need to redeclare an existing custom menu location that was created with either one of those calls.

Answer 2

there are two functions to register the menus: 1. register_nav_menu 2. register_nav_menus . The first registers only one menu location the other accepts arrays of menus. Thus, if you would like to add a new menu location you will need to use register_nav_menus();

    register_nav_menus( array(
                    'your_current_menu_location' => __( 'Your current menu label', 'your_theme' ),
                    'additional_location_' => __( 'Your additional menu label', 'your_theme'),

        //etc...
                ) );

Answer 3

You need to add this to the functions.php file for your theme, and remove the existing nav_menu function:

<?php
add_action( 'init', 'register_my_menus' );
function register_my_menus() {
register_nav_menus(
  array(
    // Add Your Current Menu Register Here And Replace The Current Code With This
    'secondary' => 'secondary' ,
    'tertiary' =>  'tertiary',
    )
  );
}
?>

To use the menu's you would place this in the template desired:

<?php wp_nav_menu( array( 'theme_location' => 'secondary' ) ); ?>

OR:

<?php wp_nav_menu( array( 'theme_location' => 'tertiary' ) ); ?>
