Sub Menu Not Working In Genesis Child Themes

A member asked this question :

no matter what I do, I cannot get the submenu to appear

Answer : The reason for this might be, some Genesis child themes include the following PHP code in functions.php which removes the sub menu from displaying below parent menu items.

add_filter( 'wp_nav_menu_args', 'essence_secondary_menu_args' );
/**
 * Reduces the secondary navigation menu to one level depth.
 */
function essence_secondary_menu_args( $args ) {

	if ( 'secondary' === $args['theme_location'] ) {
		$args['depth'] = 1;
	}

	return $args;

}

The above code targets the secondary menu. Swap out secondary to match your menu’s theme location if you need to target other menus.
