Drop Down Category Menu Not Working

Question

If you look on my website, at the top menu under Member's Only, the dropdown menu is not showing the three pages that are listed as sub-pages under the menu category. I know that the back end is fine, and this theme is an older one that I was using on another site and know this functionality works. Just thinking that maybe something is off with the JS?

This is the code in the header menu:

<div id="main-nav">
    <?php wp_nav_menu( array(
        'menu'       => 'Main Navigation',
        'container'  => false,
        'items_wrap' => '<ul class="nav">%3$s</ul>',
        'depth'      => 3,
        'walker'     => new 

Answer 1

Make a custom link with the name "Members only" and link to "#". Then add the sub-menu page.
