Remove page dropdowns

Hey everyone, I’ve done my fair share of digging before posting here. this is a last resort. I’ve done this with other themes on older version of WordPress but I cannot get it right on this theme, with this wordpress.

What I want to do it remove the list of children pages when you hover on a page on the main nav bar. I’m using the EvoLve theme, and this is the code where the site pulls the menu from.

<!--BEGIN .container-menu-->
  <div class="container nacked-menu" style="margin:0 auto;padding-bottom:10px;position:relative;z-index:99;">

     <?php if ($options['evl_main_menu'] == "1") { ?>
    <br /><br />

   <?php } else { ?>

   <div class="menu-header">

    <?php if ( has_nav_menu( 'primary-menu' ) ) { ?>

     <?php wp_nav_menu( array( 'menu_class' => 'nav', 'theme_location' => 'primary-menu' ) ); ?>

      <?php } else { ?>

	        <?php wp_page_menu( 'show_home=0' ); ?>

          <?php } ?> 

          </div> 

       <?php } ?>

Any help would be wonderful!
