Как создать пользовательское меню в Wordpress?

if ( ! function_exists( 'main_setup' ) ) :
function main_setup() {
	// This theme uses wp_nav_menu()
	register_nav_menus( array(
		'primary'	=> 'main',
		'toolbar'	=> 'toolbar',
		'social'	=> 'social',
	) );
}
endif;
add_action( 'after_setup_theme', 'main_setup' );

<?php if ( is_user_logged_in() ) : ?>
			<nav id="site-navigation" class="blog_nav" role="navigation">
				<?php wp_nav_menu( array(
					'theme_location'  => 'primary',
					'menu'            => '', 
					'container'       => 'div', 
					'container_class' => 'blog_nav_container clear',
					'container_id'    => 'blog_nav_container',
					'menu_class'      => 'blog_nav_menu',
					'menu_id'         => 'blog_nav_menu',
					'echo'            => true,
					'fallback_cb'     => '__return_empty_string',
					'before'          => '',
					'after'           => '',
					'link_before'     => '',
					'link_after'      => '',
					'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>',
					'depth'           => 0,
					'walker'          => '',
				) ); ?>
			</nav><!-- #site-navigation -->
<?php endif; ?>
