I've been asked to look at the main menu on luxmux.com, This is a Wordpress website, it has full and mobile version and the menu is different for both. For full version the menu works well and shows all the items as per Wordpress Dashboard>>Appearance>>Menu. For the mobile version however the menu adds a "- MENU -" item to the menu (to the very top). I've been asked to remove this item.
From what I see the menu is generated in header.php with this single line -
<?php wp_nav_menu( array( 'menu_id'=>'nav', 'theme_location'=>'main-navigation')); ?>
Initially I thought that I can remove a single item by using exclude, as per this example - wp_nav_menu exclude pages from menu
However, the "- MENU -" item does not have a page ID.
Look into that file and you can see
label = o.label || "- MENU -",
You'll have to know some JS to fix this issue.
