Scrolling TOC

Hi,

I did it right now with my own project. I simply used “ScrollToFixed” (https://goo.gl/ptqduY) and put that code in my header.php

  <script>

    jQuery(document).ready(function($) {
      var stickyNavTop = $('.sidebar-content').offset().top;

      var stickyNav = function(){
        var scrollTop = $(window).scrollTop();

        if (scrollTop > stickyNavTop) {
          $('.sidebar-content').addClass('sticky');
        } else {
          $('.sidebar-content').removeClass('sticky');
        }
      };

      stickyNav();

      $(window).scroll(function() {
        stickyNav();
      });
    });

  </script>

Best, Roman
