Add-On plugin for Advanced Custom Fields (ACF) that adds a 'Nav Menu' Field type.
Side Menu(this will cause the Field Name to be
Nav Menu HTML
<?php if( get_field( 'side_menu' ) ) : ?> <div class="widget-area"> <?php the_field( 'side_menu' ); ?> </div> <?php endif; ?>
Finally, create or edit a page, select a menu in the Side Menu field, and view the page to see that menu in the sidebar!
So that you can style it yourself. I don't want to step on your toes :)
First, check that you added the necessary ACF code to your templates. If you don't know what I'm talking about, read up on how to use Advanced Custom Fields. If you're already familiar with ACF and you still can't figure out why the menu isn't showing up, start a new support thread, include details and a little code, and I'll do my best to help you.
