如何将菜单的可点击区域限制为文本？

Question

Why is the whole width clickable and how can I change that?

Obviously the only clickable area should be the text when visible, nothing else.

I've tried display: inline-block but it messed up the menu.

Fiddle

Thanks.

HTML

<div class="wrapper">
<ul>
    <li class="menu-level-1"><a href="#">Item 1</a>
        <ul class="menu-level-2">
        <li><a href="#">Item 1-1</a></li>
        <li><a href="#">Item 1-2</a></li>
        </ul>
    </li>
    <li class="menu-level-1"><a href="#">Item 2</a>
        <ul class="menu-level-2">
        <li><a href="#">Item 2-1</a>
            <ul class="menu-level-3">
            <li><a href="#">Item 2-1-1</a></li>

        <li><a href="#">Item 4-2</a></li>

    </li>
    </ul>
</div>

CSS

body{
    margin: 0px;
    border: 0;
    overflow: hidden;
}

ul {
    list-style: none;
    margin: 0;
    padding: 0;
    color: #000000;
}

ul li {
    position: relative;
}

li ul {
    position: absolute;
    left: 120px;
    top: 0;
    display: none;
}

ul li a {
    text-decoration: none;
    color: #000000;
}

.menu-level-1 {
    position: relative;
    top: 20px;
    left: 20px;
    font-family: Arial, Helvetica, sans-serif;
    font-size: 11px;
    font-weight: normal;
    line-height: 15px;
    letter-spacing: 0em;
    text-transform: uppercase;
}

.menu-level-2 {
    position: fixed;
    top: 20px;
    font-family: Arial, Helvetica, sans-serif;
    font-size: 11px;
    font-weight: normal;
    line-height: 15px;
    letter-spacing: 0em;
    text-transform: uppercase;
}

Answer 1

The whole width is clickable because li elements have the list-item display, whose behavior specifies that their width is 100%. This is misleading because only the anchor tags have the pointer cursor.

I updated your fiddle ( http://jsfiddle.net/180xhfwk/2/ ) with the following:

$('.menu-level-1 a').on('click', function() {
    var parent = $(this).parent();

    ...
});

It now binds the click listener to the the anchor tags themselves, rather than the .menu-level-1 things and functions as I think you expect it to.

Answer 2

Just change your CSS and use display: table.

ul li {
    position: relative;
    display: table;
}

Answer 3

Instead of using click event for li , use click event for anchor and in traversing use parent()

Jquery:

$('.menu-level-2').hide();
$('.menu-level-1 > a').on('click', function(){      
  if(!($(this).parent().children('.menu-level-2').is(':visible'))){
      $('.menu-level-2').slideUp();
      $(this).parent().children('.menu-level-2').slideDown();
    } else {
    $('.menu-level-2').slideUp();
  }
});
$('.menu-level-2').on('click', function(e){
  e.stopPropagation();
});
