Displaying a sub-sub-menu on hover of menu with CSS - html

Question

I need to display sub-sub-menu on hover of my sub-menu. So far I did code to display menu -> sub-menu on menu click, but to proceed I want a functionality to display sub-sub-menu on hover of my sub-menu. Can somebody help me to achieve the same?
var ddmenuitem = 0;
function jsddm_open() {
jsddm_close();
ddmenuitem = $(this).find('ul.submenu').css('display', 'block');
// $(this).find('div.subsubmenu').css('display','none');
}
function jsddm_close() {
if (ddmenuitem) ddmenuitem.css('display', 'none');
}
$(document).ready(function() {
$('#topnav > ul > li').bind('click', jsddm_open)
$('#topnav > ul > li > a').click(function(ev) {
if ($(this).hasClass('current')) {
ev.preventDefault();
}
if ($(this).attr('class') != 'active') {
$('#topnav ul li a').removeClass('active');
$(this).addClass('active');
}
});
});
#topnav {
float: left;
width: 600px;
height: 30px;
background: black;
margin-top: 10px;
position: relative;
font-size: 15px;
margin-left: 30px
}
#topnav ul {
list-style: none;
padding: 0px;
margin: 0px;
}
#topnav ul li {
float: left;
margin: 0;
padding: 0;
}
#topnav ul li a {
padding: 5px 15px;
color: red;
text-decoration: none;
display: block;
font-weight: bold;
}
#topnav ul li a:link {

}
#topnav ul li a:visited {

Try the following snippet without using jquery or javascript, you can get it done using only css. And have updated according to your question
#nav {
list-style: none inside;
margin: 0;
padding: 0;
text-align: center;
}
#nav li {
display: block;
position: relative;
float: left;
background: #000000;
}
#nav li a {
display: block;
padding: 0;
text-decoration: none;
width: 200px;
line-height: 35px;
color: #fff;
}
#nav li li a {
font-size: 80%;
}
#nav li:hover {
background: #ff0000;
}
#nav ul {
position: absolute;
padding: 0;
left: 0;

#nav li:hover ul {
display: block;
}
#nav li li:hover ul {
display: block;
margin-left: 200px;
