website display issue - Elements in menu-bar not showing when they have sub-menus

I developed a website and recognized an error during the cross browser testing.

In Internet Explorer 11 elements in my menu-bar are not shown when they have sub-menus.

Here is an image to show the error:

the menu-bar in ie11

In the Edge Browser things are a little bit more tricky. The sub-menu elements are shown in the first place. But when one hovers over the element, so that the sub-menu item list appears and then hover over an element which contains a sub-sub-menu, every menu item with a sub-menu disappears in the menu-bar.

Here is an image from Edge:

The link to my testpage is http://undefined.bplaced.net

The menu-bar works well in every other browser I tested (latest version of FireFox, Chrome, Safari, Andriod, iPhone), just the Microsoft browsers are 'special'.

I'm not sure where/how to search for that error, maybe it's caused by the CSS (I prefixed my CSS for IE/Edge) or jQuery/JavaScript or maybe it's even the ul li HTML markup, I don't know.

here is the HTML, CSS, and JavaScript I applied to the menu:

jQuery(document).ready(function($) {

  // add JS-classes into the HTML-Tag
  $('html').addClass('js');

  // add classes for sub menus and sub menus toggle button
  $(".site-nav li > ul").parent('li').addClass('has-sub-menu');
  $(".site-nav li > ul").addClass('sub-menu');

  // create button for expand- und collapse the menu and render it into the header
  var create_toggle_nav_button = ['<div class="toggle-site-nav">Menu</div>'].join("");
  $("header").append(create_toggle_nav_button);

  // create button for expand- und collapse the sub menu  for mobile view and add them to all sub menus
  var create_sub_toggle_button = ['<span class="toggle-sub-menu"></span>'].join("");
  $(".has-sub-menu > a").after(create_sub_toggle_button);

  // define variables
  var $menu = $('.site-nav'),
    $toggle_nav = $('.toggle-site-nav'),
    $toggle_sub_menu = $('.toggle-sub-menu');

  // collapse and expand function of the main menu
  $toggle_nav.click(function(e) {
    e.preventDefault();
    $menu.slideToggle();
  });

  // collapse and expand function of the drop down menu for mobile view
  $toggle_sub_menu.click(function(e) {
    e.preventDefault();
    var $this = $(this);
    $this.toggleClass('active').next('ul').slideToggle();
  });

  // display hidden elements again, when browserwindow is resized by user
  $(window).resize(function() {
    var w = $(window).width();
    if (w > 900) {
      $('.site-nav').removeAttr('style');
      $('.sub-menu').removeAttr('style');
    }
  });

  // collapse navigation automatically to the left, when it run out of the viewport
  $(".site-nav .has-sub-menu").on('mouseenter mouseleave', function(e) {

    var nav_element = $('ul:first', this);
    var element_offset = nav_element.offset();
    var element_offset_left = element_offset.left;
    var element_width = nav_element.width();
    var viewport_width = $(window).width();

    var element_in_viewport = (element_offset_left + element_width <= viewport_width);

    if (!element_in_viewport) {
      $(this).addClass('sub-left');
    } else {
      $(this).removeClass('sub-left');
    }
  });

I would really appreciate any hint how to track down this bug.

Solution

  • The rule .js .has-sub-menu sets position:relative; top:100% on those items, and that’s what makes them disappear in IE.

    Not sure what top:100% was supposed to achieve here in the first place, but without it, it looks fine (and does in Chrome as well), so I guess you can just completely remove that.
