Nxeed Tree Menu is a simple jQuery plugin to create an accordion-style vertical tree menu that is collapsible and expandable with smooth sliding effects.

How to use it:

1. Include jQuery library and the tree menu script in the document.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="path/to/jquery.ntm.js"></script>

2. Create a multi-level tree menu using nested Html lists.

<div class="tree-menu demo" id="tree-menu">
  <ul>
    <li><a href="#">Menu 1</a></li>
    <li><a href="#">Menu 2</a></li>
    <li><a href="#">Menu 3</a>
      <ul>
        <li><a href="#">Submenu 1</a></li>
        <li><a href="#">Submenu 2</a></li>
        <li><a href="#">submenu 3</a></li>
      </ul>
    </li>
  </ul>
</div>

3. Style the tree menu whatever you like.

.tree-menu ul { list-style: none; }

.tree-menu > ul { padding: 0; }

.tree-menu a {
  display: block;
  vertical-align: middle;
  text-decoration: none;
  padding: 6px;
  background-color: #efefef;
  border-radius: 4px;
  margin-bottom: 1px;
  color: #002888;
  -moz-transition: background-color 0.25s linear;
  -webkit-transition: background-color 0.25s linear;
  -o-transition: background-color 0.25s linear;
  transition: background-color 0.25s linear;
  -moz-transition-delay: 0.15s;
  -webkit-transition-delay: 0.15s;
  -o-transition-delay: 0.15s;
  transition-delay: 0.15s;
}

.tree-menu a:hover {
  color: #f53d3e;
  -moz-transition: background-color 0.1s linear;
  -webkit-transition: background-color 0.1s linear;
  -o-transition: background-color 0.1s linear;
  transition: background-color 0.1s linear;
}

.tree-menu .active > a:hover,
.tree-menu .selected > a,
.tree-menu a:hover { background-color: #c6cdde; }

.tree-menu .selected > a {
  color: #f53d3e;
  font-weight: bold;
  text-decoration: none;
}

.tree-menu .active > a { background-color: #e1e3e9; }

.tree-menu .closed > a,
.tree-menu .opened > a {
  padding-left: 24px;
  background-position: 4px 8px;
  background-repeat: no-repeat;
}

.tree-menu .closed > a { background-image: url(../img/icon-expand.gif); }

.tree-menu .opened > a { background-image: url(../img/icon-collapse.gif); }

4. To enable the tree menu, just simply call the function on the parent element.

$(document).ready(function() {
  $('.demo').ntm();
});

5. Available parameters.

var defaults = {
  autoParentDetection: true,
  autoActiveDetection: true,
  itemsUniqueClasses: true,
  parentClass: 'parent',
  activeClass: 'active',
  selectedClass: 'selected',
  expandClass: 'opened',
  collapseClass: 'closed',
  spoilerButtonClickMinX: 4,
