Bootstrap clickable menu on hover

Question

I have customized using jquery the bootstrap navigation whereby instead of clicking to enable the dropdown menu you can simply hover. However, I am trying to get it so the first menu is clickable as currently it is not. For example currently BLOG isn't clickable but I would like it to be. The other categories are clickable.

Does anyone have any experience in this on bootstrap? It is being built on wordpress. The jquery I used to allow the menu to show on hover is:

jQuery(document).ready(function() {

    var mq = window.matchMedia('(min-width: 768px)');
  if (mq.matches) {
    jQuery('ul.navbar-nav li').addClass('hovernav');
  } else {
    jQuery('ul.navbar-nav li').removeClass('hovernav');
  };
    /*
    The addClass/removeClass also needs to be triggered
  on page resize <=> 768px
    */
  if (matchMedia) {
    var mq = window.matchMedia('(min-width: 768px)');
    mq.addListener(WidthChange);
    WidthChange(mq);
  }
    function WidthChange(mq) {
    if (mq.matches) {
      jQuery('ul.navbar-nav li').addClass('hovernav');
    } else {
      jQuery('ul.navbar-nav li').removeClass('hovernav');
    }
  };


});

The css is:

@media (min-width: 768px) {
    .navbar-nav .caret {
        display:none;
    }

    .navbar-nav .open ul {
        display:none;
    }

    .navbar-default .navbar-nav > .open > a,.navbar-default .navbar-nav > .open > a:hover,.navbar-default .navbar-nav > .open > a:focus,.navbar-default .navbar-nav > .active > a,.navbar-default .navbar-nav > .active > a:hover,.navbar-default .navbar-nav > .active > a:focus {

        color:#555;
    }

    .navbar-inverse .navbar-nav > .hovernav > a {
        color:#969696;
    }

    .navbar-default .navbar-nav > .hovernav:hover > a,.navbar-default .navbar-nav > .hovernav:hover > a:hover,.navbar-default .navbar-nav > .hovernav:hover > a:focus {
        color:#333;

    }

    .navbar-inverse .navbar-nav > .hovernav:hover > a,.navbar-inverse .navbar-nav > .hovernav:hover > a:hover,.navbar-inverse .navbar-nav > .hovernav:hover > a:focus {
        color:#F7F7F7;
        background:transparent;
    }

    .navbar-default .navbar-nav > li:hover {
        background:#e7e7e7;
    }

    .navbar-inverse .navbar-nav > li:hover {
        background:#080808;
    }

    .navbar-nav .hovernav:hover > .dropdown-menu {
        display:block;
    }
}

Problems using matchMedia/media queries to accomplish what you're doing:

Media queries for many touch devices are the same as desktop.

Hover does not exist on touch. IOS takes a hover and one click triggers the dropdown 2 clicks get to the link, BUUUT android doesn't work this way. So on touch devices those drop menus won't be accessible. How to do this correctly:

1. Detect touch and no-touch on Android, IOS, and Windows 8 phones.

2. Remove the Attribute data-toggle on the .dropdown a link -- removing this allows the click to work on that toggle.

3. Wrap the removing attribute in an if statement if no-touch

4. Wrap the hover script in a no-touch if statement

5. Have a fallback for touch devices so they can get to the first menu item

SAMPLE HTML with fallback for the link:

 <!-- Static navbar -->
  <div class="navbar navbar-default" role="navigation">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Project name</a>
    </div>
    <div class="navbar-collapse collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li class="dropdown">
          <a href="http://getbootstrap.com" data-toggle="dropdown" data-hover="dropdown" data-delay="1000" data-close-others="false">Blog <b class="caret"></b></a>
          <ul class="dropdown-menu">


            <!-- add for touch they won't be able to get to the link -->
            <li class="mobile-link"><a href="blog.html">Latest News</a></li>

            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li class="dropdown-header">Nav header</li>
            <li><a href="#">Separated link</a></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li class="active"><a href="./">Default</a></li>
        <li><a href="../navbar-static-top/">Static top</a></li>
        <li><a href="../navbar-fixed-top/">Fixed top</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>

I tested this on Android. Test this on IOS, Windows 8, and other devices before awarding/accepting. Should work smoothly.

$('body').on('mouseover', '.dropdown-toggle', function(e){
    $(e.currentTarget).trigger('click')
})

or instead of ".dropdown-toggle" you could use the id of the element that triggers the dropdown
