If you are using the the WordPress Function register_nav_menus() , it should be fairly simple.
In your functions.php file you’ll need to register 3 separate menu’s, something like this:
<?php
add_action( 'init', 'register_my_menus' );
function register_my_menus() {
register_nav_menus(
array( 'first' => 'first', 'second' => 'second', 'third' => 'third', )
);
}
?>With the menu’s now registered you just need to place them where they go in your theme files like so:
The First Menu (maybe in the header.php file)
<div id="menu"> <?php wp_nav_menu( array( 'theme_location' => 'first' ) ); ?> </div>
The Second Menu (maybe in the sidebar.php file)
<div id="menu"> <?php wp_nav_menu( array( 'theme_location' => 'second' ) ); ?> </div>
The Third Menu (maybe in the footer.php file)
<div id="menu"> <?php wp_nav_menu( array( 'theme_location' => 'third' ) ); ?> </div>
The final step is to go to Appearance>Menu’s and create the 3 menu’s,
name them and choose the pages that will go with them from within the Admin Menu Settings.
