Fullwidth subemenu always sticky, even with Hamburger menu active on desktop

Hi,
To have a sticky sub-menu on your desktop with the burger menu, and on your mobile without the sticky header, Try adding this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function desktop_burger_menu_sub_menu_sticky() { ?>
<script>
window.addEventListener('DOMContentLoaded', function() {
  (function($){
  	var width = $(window).width();
    var $stickyTop = $('#sub_menu1');
    if (width <= 989) {
    $stickyTop.waypoint(function(direction) {
      if (direction === 'down') {
         $stickyTop.addClass('sticky-top');
      }
      if (direction === 'up') {
         $stickyTop.removeClass('sticky-top');
      }
    }, {
      offset: '0%'
    });
    }
	else if (width >= 990) {
    $stickyTop.waypoint(function(direction) {
      if (direction === 'down') {
         $stickyTop.addClass('sticky-top');
      }
      if (direction === 'up') {
         $stickyTop.removeClass('sticky-top');
      }
    }, {
      offset: '95px'
    });
    }
  })(jQuery);
});
</script>
  <?php
}
add_action('wp_footer', 'desktop_burger_menu_sub_menu_sticky');

Please ensure to copy the code from the forum and not an email notification so the symbols are not converted.
also add this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

@media only screen and (max-width: 989px) { 
.responsive #top #sub_menu1.av-submenu-container.sticky-top {
	position:fixed!important;
	top:0!important;
	z-index:600!important;
}
}
@media only screen and (min-width: 990px) { 
.responsive #top #sub_menu1.av-submenu-container.sticky-top {
	position:fixed!important;
	top:95px!important;
	z-index:600!important;
}
}

This accounts for the mobile switch at 989px when your typical header is no longer sticky, but the sub-menu will be sticky at the top.
In the css & script you may need to adjust the top height, my text site header was 95px high, if yours is different please change.
If you have trouble with this please include a admin login in the private content area so we can take a closer look.
