How to hide drop down menu on scroll?

Question

JavaScript

Good afternoon.
In the mobile version of this site , when you click on the "burger" menu drops out. But how can you hide it on scroll down if it is open without clicking on the burger again? Now implemented like this:

(function ($) {
  $(document).ready(function(){
  $(function () {
    $(window).scroll(function () {
      if ($(this).scrollTop() > 100) {
        $('#dropmenu').fadeOut();
      }
    });
  });
});

When scrolling the menu closes, but then does not open when you click on "burger")
