make CSS hover menu click rather than hover

Question

I have a CSS/HTML menu with this CSS code:

#nav {
    background-color:#F36F25;
    margin:0 0 5px 0;
    width: 100%;
    height:35px;
    left:0;
    z-index:1;
    border-top:2px solid #FFFFFF;
    border-bottom:2px solid #FFFFFF;
}
#nav>li {
    float:left;
    list-style:none;
}
#nav li:hover ul {
    position:absolute;
    display:block;
    z-index:9999;
}
#nav li a {
    display: inline-block;
    padding: 8px;
    margin:0;
    background: #F36F25;
    text-decoration: none;
    color: #FFFFFF;
    border:1px solid #F36F25;
}
#nav li:hover > a, #nav li a.active {
    color:#F36F25;
    background: #FFFFFF;
    border:1px solid #F36F25;
    cursor:pointer;
}
#nav li ul {
    position:absolute;
    display: none;
    list-style:none;
    margin:0;
}
#nav li ul li {
    margin-top:0;
    margin-right:0;
    margin-bottom:0;
    margin-left:-40px;
}
#nav li ul li a {
    background-color: #F36F25;
    color:#FFFFFF;
    border:1px solid #F36F25;
    width:145px;
}
#nav li ul li a:hover {
    background-color: #FFFFFF;
    color:#F36F25;
    border:1px solid #f36f25;
}
.clearfix:after {
   content: " "; /* Older browser do not support empty content */
   visibility: hidden;
   display: block;
   height: 0;
   clear: both;
}
.clearfix:after {
  content: "";
  display: table;
  clear: both;
}

How can i ensure the onhover events stay but make the sub menus show on click rather than when the users hovers on the parent link?

i am happy to use Jquery or Javascript if needed but full css would be good if possible

Answer 1

I think you can :focus instead of :hover like this update this code

or through js fiddle

 #nav li:focus ul { position:absolute; display:block; z-index:9999; } 

Answer 2

Let's suppose you want to change display strategies when you click on your element. Let's suppose your element has a selector . In that case, you can define this event with jQuery:

$(selector).click(function() {
    if ($(this).hasClass("clicked")) {
        $(this).removeClass("clicked");
    } else {
        $(this).addClass("clicked");
    }
});

And you need to have some CSS for .clicked as well. Let us suppose your selector is #foo . Then you need rules like this:

#foo {
    /*Add some stuff*/
}

#foo.clicked {
    /*Add some stuff*/
}
