Bourbon Refill Navigation Menu slide up on click

Question

I am using the Bourbon Refill navigation menu, and want to modify it so when a link is clicked on in small mode the menu slides back up. At the moment the menu drops down, but when a menu item is clicked the menu stays dropped down. As I am using scroll-on-page with a fixed top menu this means a lot of the content is hidden behind the menu.

Here is the code on Codepen:

My existing code is below:

HTML

<header class="navigation" role="banner">
<div class="navigation-wrapper">
<a href="javascript:void(0)" class="logo">
<img src="https://raw.githubusercontent.com/thoughtbot/refills/master/source/images/placeholder_logo_1_dark.png" alt="Logo Image">
</a>
<a href="javascript:void(0)" class="navigation-menu-button" id="js-mobile-menu">Menu</a>
<nav role="navigation">
  <ul id="js-navigation-menu" class="navigation-menu show">
    <li class="nav-link"><a href="javascript:void(0)">About Us</a></li>
    <li class="nav-link"><a href="javascript:void(0)">Contact</a></li>
    <li class="nav-link"><a href="javascript:void(0)">Testimonials</a></li>
    <li class="nav-link"><a href="javascript:void(0)">Sign up</a></li>
  </ul>
</nav>

.navigation {
$large-screen: em(860) !default;

// Mobile view

// Nav items
ul li.nav-link {

}

li.nav-link a {
display: inline-block;

@include media ($large-screen) {

}
}
}

JS

$(document).ready(function() {
var menuToggle = $('#js-mobile-menu').unbind();
$('#js-navigation-menu').removeClass("show");

menuToggle.on('click', function(e) {
e.preventDefault();
$('#js-navigation-menu').slideToggle(function(){
if($('#js-navigation-menu').is(':hidden')) {
$('#js-navigation-menu').removeAttr('style');
  }
});
});
});

Help greatly appreciated

Answer 1

Check out the following demo tested working in small and large version as your expectation.

EDIT 2

Updated toggling for small version as per your requirement.

Codepen

jQuery

function smallVersion() {
  $("#js-navigation-menu a").on('click', function(e) {
    $('#js-navigation-menu').slideToggle(function() {
      if ($('#js-navigation-menu').is(':hidden')) {
        $('#js-navigation-menu').removeAttr('style');
      }
    });
  });
}

function dothis(){
    var ww = $(window).width();
    var emToPx = 53.75 * parseFloat($("html").css("font-size"));
    if( ww < emToPx ) {
        smallVersion();
    }
}

$(document).ready(function() {
  var menuToggle = $('#js-mobile-menu').unbind();
  $('#js-navigation-menu').removeClass("show");

  menuToggle.on('click', function(e) {
    e.preventDefault();
    $('#js-navigation-menu').slideToggle(function(){
      if($('#js-navigation-menu').is(':hidden')) {
        $('#js-navigation-menu').removeAttr('style');
      }
    });
  });

  dothis();
});
