[html/js]点击标题出现下拉列表

效果

初始

点击后

参考代码

<!DOCTYPE html>
<html>
<head>
<title>Layer group example</title>
<script src="js/jquery-1.11.1.min.js"></script>

<link rel="stylesheet" href="css/bootstrap.min.css">
<script src="js/bootstrap.min.js"></script>

<style>
    #layertree li > span {
      cursor: pointer;
    }
</style>

<style>
    ul,ol {
        list-style: none
    }
</style>

</head>
<body>

<div id="layertree" class="span6">
  <span>图层列表</span>
  <ul class='layer-list'>
      <li><input type="checkbox"><span>Food insecurity layer</span>
        <fieldset>
          <input class="opacity" type="range" min="0" max="1" step="0.01"/>
        </fieldset>
      </li>

      <li><input type="checkbox"><span>World borders layer</span>
        <fieldset>
          <input class="opacity" type="range" min="0" max="1" step="0.01"/>
        </fieldset>
      </li>
  </ul>
</div>
<script>

$('#layertree li > span').click(function() {
  $(this).siblings('fieldset').toggle();
}).siblings('fieldset').hide();

</script>
</body>
</html>

其中：

1. <html>标签<ul>表示无序列表；<ol>比奥斯有序列表

2. 以下格式，表示每一小项的前边没有默认的黑点

ul,ol {
    list-style: none
}
