WordPress Menu as Select Dropdown

WordPress menus display as unordered lists by default. You might want to display them as a select menu though. Below is an example of creating a menu ‘walker’ that will render it as a select menu. When you are displaying your menu using wp_nav_menu(), include 'walker' => new Walker_Nav_Menu_Dropdown() to tell WordPress to use this type of formatting rather than the default.

<?php
// Nav Menu Dropdown Class
include_once( CHILD_DIR . '/lib/classes/nav-menu-dropdown.php' );
/**
* Mobile Menu
*
*/
function be_mobile_menu() {
wp_nav_menu( array(
'theme_location' => 'mobile',
'walker' => new Walker_Nav_Menu_Dropdown(),
'items_wrap' => '<div class="mobile-menu"><form><select onchange="if (this.value) window.location.href=this.value">%3$s</select></form></div>',
) );
}
add_action( 'genesis_before_header', 'be_mobile_menu' );
