Bootstrap Style Dropdown Menu Plugin - jQuery Dropdown.js

A dead simple jQuery dropdown plugin which lets you create Bootstrap-style dropdown menus from standard HTML unordered lists.

How to use it:

1. Load the stylesheet dropdown.css in the document that provides the default styles for the dropdown menu.

<link rel="stylesheet" href="dropdown.css">

2. Create an HTML unordered list for the dropdown menu.

<div class="dropdown">
  <div class="more-btn">
    Default Dropdown Menu
    <span class="triangle"></span>
  </div>
  <ul class="dropdown-menu">
    <li>
      <a href="javascript:;">jQuery</a>
    </li>
    <li>
      <a href="javascript:;">Script</a>
    </li>
    <li>
      <a href="javascript:;">.Net</a>
    </li>
  </ul>
</div>

3. Load jQuery JavaScript library and the JavaScript file dropdown.js at the end of the document. Done.

<script src="https://code.jquery.com/jquery-1.12.4.min.js" 
        integrity="sha384-nvAa0+6Qg9clwYCGGPpDQLVpLNn0fRaROjHqs13t4Ggj3Ez50XnGQqc/r8MhnRDZ" 
        crossorigin="anonymous">
</script>
<script src="dropdown.js"></script>

4. To set the alignment to Right, just add the dropdown-right class to the top container.

<div class="dropdown dropdown-right">
  ...
</div>

5. Override the default CSS to create your own styles.

.dropdown-menu {
  display: none;
  position: absolute;
  top: 100%;
  left: 0;
  text-align: left;
  border: 1px solid #ccc;
  border-radius: 4px;
  box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
  list-style: none;
  padding: 5px 0;
  margin: 2px 0 0 0;
}

.dropdown-menu > li > a {
  display: block;
  color: #333;
  white-space: nowrap;
  text-decoration: none;
  padding: 3px 20px;
}

.dropdown-menu > li > a:hover { background-color: #f5f5f5; }
