multiple menu

You could use the same theme and switch out the menu based on a simple token variable.

Set up a token in the MiniMU options to filter from, in this example I’ve used ‘language’ as the token name and ‘spanish’ as the variable:

Next, configure your menu names to work with token variables. ‘menu’ will work as default, ‘menu_spanish’ will work on domains with ‘spanish’ set as the language token variable.

Then, drop this code where ever you want the menu to appear in your theme:

<?php
$token = MiniMU::get_token('language'); // Change language to your token variable.
if ($token == '') { $menuToken = ''; } else { $menuToken = '_' . $token; };
$defaults = array(
	'menu'            => 'menu' . $menuToken,
	'menu_class'      => 'nav-classes',
	'echo'            => true,
	'fallback_cb'     => 'wp_page_menu',
	'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>'
);
wp_nav_menu( $defaults );
?>

Let me know if this works for you. 🙂
