I installed a plugin for a dropdown menu (Max Mega Menus) but my wordpress theme (Spacing) is overriding it. I followed the instructions on the MMM website on removing residual styling so that the plugin would work but when I deleted the codes as instructed (I think I picked the right one) then the menu disappeared altogether. Here are the instructions I was following: https://www.maxmegamenu.com/documentation/faqs/removing-residual-styling/ Here is the current coding. I tried deleting every combination of things besides the wp_nav_menu part, as instructed.
<div id="header">
<div id="wrapper">
<div class="container clearfix">
<div id="navigation">
<?php wp_nav_menu(array('menu' => 'custom_menu')); ?>
<?php if($of_option['st_responsive']) responsive_select_nav() ?>
</div>
</div>
</div>
