Function JavaScript : on Menu CSS HTML

I have problems with my menu. Currently, it's only working on the submenu dropdown.

How to enable it on the main menu too?



document.addEventListener('click', function(e) {
e = e || window.event;
var target = e.target || e.srcElement;
if (target.parentElement.className.indexOf('has-submenu') > -1) {
e.target.classList.toggle('open');
}
}, false);

#menu {

height: 35px;
border-bottom: 4px solid #eeeded

Answer

Here's a working example. You only need to catch click events for all the elements with class has-submenu and toggle classes etc accordingly.

document.addEventListener('click', function(e) {
  e = e || window.event;
  var target = e.target || e.srcElement;
  if (target.parentElement && target.parentElement.className.indexOf('has-submenu') > -1) {
    e.target.parentElement.classList.toggle('open');
  }
}, false);
#menu {
  background: #343434;
  color: #eee;
  height: 35px;
  border-bottom: 4px solid #eeeded
}

#menu ul,
#menu li {
  margin: 0 0;
  padding: 0 0;
  list-style: none
}

#menu ul {
  height: 35px
}

#menu li {
  float: left;
  display: inline;
  position: relative;
  font: bold 12px Arial;
  text-shadow: 0 -1px 0 #000;
  border-right: 1px solid #444;
  border-left: 1px solid #111;
  text-transform: uppercase
}

#menu li:first-child {
  border-left: none
}

#menu a {
  display: block;
  line-height: 35px;
  padding: 0 14px;
  text-decoration: none;
  color: #eee;
}

#menu li:hover > a,
#menu li a:hover {
