Template Tags/register nav menu

Description

Registers a menu location to use with navigation menus. Even if you explicitly set theme support for navigation menus, this function must be in your theme's functions file for WordPress to recognize navigation menu support in your theme.

Usage

 <?php register_nav_menu( 'your-menu-handle', 'Your Menu Label' ); ?> 

Example

This is the code you need in your functions.php to enable native navigation menu support: <?php
register_nav_menu('main', 'Main navigation menu');
?>
