我一直在尝试创建一个使用尽可能多的 CSS 和尽可能少的 JS（仅用于状态等）的树（如目录树），我想知道是否有一些好的现有树插件用于引导程序或jquery-ui 引导程序。

作为参考或对这个问题感到困惑的人，我正在寻找类似dynatree的引导程序。

在Vitaliy 的 CSS和Mehmet 的 jQuery 的基础上，我将a标签更改为标签，并在我的 Bootstrap 树小部件span中加入了一些Glyphicons和徽章。

例子： 我对 Bootstrap 树小部件的看法

为了获得额外的荣誉，我创建了一个Github 图标GitHub 项目来托管用于将此树组件添加到 Bootstrap 的 jQuery 和 LESS 代码。请参阅http://jhfrench.github.io/bootstrap-tree/docs/example.html上的项目文档。

或者，这里是生成 CSS 的 LESS 源（可以从jsFiddle获取 JS ）：

@import "../../../external/bootstrap/less/bootstrap.less"; /* substitute your path to the bootstrap.less file */
@import "../../../external/bootstrap/less/responsive.less"; /* optional; substitute your path to the responsive.less file */

/* collapsable tree */
.tree {
    .border-radius(@baseBorderRadius);
    .box-shadow(inset 0 1px 1px rgba(0,0,0,.05));

你能相信下图中的树形视图没有使用任何 JavaScript，而是仅依赖于 CSS3 吗？看看这个CSS3 TreeView，它与 Twitter BootStrap 很相配：

如果有人想从 Harsh 的答案中获得垂直版本的树视图，您可以节省一些时间：

.tree li {
    margin: 0px 0;

    list-style-type: none;
    position: relative;
    padding: 20px 5px 0px 5px;
}

.tree li::before{
    content: '';
    position: absolute; 
    top: 0;
    width: 1px; 
    height: 100%;
    right: auto; 
    left: -20px;
    border-left: 1px solid #ccc;
    bottom: 50px;
}
.tree li::after{
    content: '';
    position: absolute; 
    top: 30px; 
    width: 25px; 
    height: 20px;
    right: auto;

    font-size: 11px;
    border-radius: 5px;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
}

/*Remove connectors before root*/

对于那些仍在使用 CSS3 搜索树的人，这是我在网上找到的一段很棒的代码：

http://thecodeplayer.com/walkthrough/css3-family-tree

HTML

<div class="tree">
  <ul>
    <li>
      <a href="#">Parent</a>
      <ul>
        <li>
          <a href="#">Child</a>
          <ul>
            <li>
              <a href="#">Grand Child</a>
            </li>
          </ul>
        </li>
        <li>
          <a href="#">Child</a>
          <ul>
            <li><a href="#">Grand Child</a></li>
            <li>
              <a href="#">Grand Child</a>
              <ul>

如果有人想要 Vitaliy Bychik 的回答中的树视图的可扩展/可折叠版本，您可以节省一些时间:)

http://jsfiddle.net/mehmetatas/fXzHS/2/

$(function () {
    $('.tree li').hide();
    $('.tree li:first').show();
    $('.tree li').on('click', function (e) {
        var children = $(this).find('> ul > li');
        if (children.is(":visible")) children.hide('fast');
        else children.show('fast');
        e.stopPropagation();
    });
});

另一个很棒的 Treeview jquery 插件是http://www.jstree.com/

对于高级视图，您应该检查 jquery-treetable
