Minimal Accordion/Sliding Box Plugin - Accordion.js

A minimal accordion engine written in jQuery that enables the users to collapse and expand sectioned content just like a sliding box.

The plugin simply provides a basic accordion logic to your sectioned content. Feel free to apply custom styles & animations to the accordion panels using your own CSS.

How to use it:

1. Add accordion headers (controls) and panels to the accordion interface as follows:

<div id="my-accordion" class="accordion">
  <div class="group">
    <a class="control" href="#">Accordion #1 <span class="expand">&#9660;</span><span class="collapse">&#9650;</span></a>
    <div class="box">
      <div class="inner">
        Accordion 1 Content
      </div>
    </div>
  </div>
  <div class="group">
    <a class="control" href="#">Accordion #2 <span class="expand">&#9660;</span><span class="collapse">&#9650;</span></a>
    <div class="box">
      <div class="inner">
        Accordion 2 Content
      </div>
    </div>
  </div>
  <div class="group">
    <a class="control" href="#">Accordion #3 <span class="expand">&#9660;</span><span class="collapse">&#9650;</span></a>
    <div class="box">
      <div class="inner">
        Accordion 3 Content
      </div>
    </div>
  </div>
</div>

2. Add jQuery JavaScript library and the Accordion.js script to the webpage.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/js/accordion.js"></script>

3. Initailize the accordion plugin and done.

$(function() {
  $('#my-accordion').accordion();
});

4. Enable the smooth slide up/down animations. Default: false.

$(function() {
  $('#my-accordion').accordion({
    animation: true,
    speed: 500 // default: 200
  });
});

5. Determine whether to allow multiple accordion panels to be expanded at a time. Default: false.

$(function() {
  $('#my-accordion').accordion({
    multiple: true
  });
});

6. Customize the appearance of the accordion with CSS.

.accordion {
  border-bottom: 1px solid #9a9a9a;
}

.accordion .control {
  position: relative;
  text-decoration: none;
  display: block;
  font-weight: bold;
  font-size: 16px;
  line-height: 40px;
  padding: 0.4em 1em;
  color: #333333;
  background-color: #f5f5f5;
  background-image: -moz-linear-gradient(top, #ffffff, #e6e6e6);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#ffffff), to(#e6e6e6));
  background-image: -webkit-linear-gradient(top, #ffffff, #e6e6e6);
  background-image: -o-linear-gradient(top, #ffffff, #e6e6e6);
  background-image: linear-gradient(to bottom, #ffffff, #e6e6e6);
  background-repeat: repeat-x;
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#ffffffff', endColorstr='#ffe6e6e6', GradientType=0);
  filter: progid: DXImageTransform.Microsoft.gradient(enabled=false);
}

.accordion .control .collapse {
  position: absolute;
  right: 10px;
  top: 7px;
}

.accordion .control .expand {
  position: absolute;
  right: 10px;
  top: 7px;
}

.accordion .control i {
  font-size: 1.2em;
  color: #009900;
}

.accordion .control:hover {
  text-decoration: none;
}

.accordion .group {
  border: 1px solid #9a9a9a;
  border-bottom: none;
}

.accordion .group .box {
  border-top: 1px solid #9a9a9a;
  padding: 0;
  margin: 0;
}

.accordion .group .box .inner {
  padding: 1em;
}

.accordion .group.open .control {
  background-color: #e4e4e4;
  background-image: none;
}
