我一直在尝试创建一个树(像目录树),尽可能多地使用CSS和尽可能少的JS (仅用于状态等),我想知道是否有一些好的现有的bootstrap或jquery-ui bootstrap的树插件。
作为参考或对这个问题感到困惑的人,我正在寻找像dynatree这样的引导程序。

如果有人想从Harsh的答案中获得treeview的垂直版本,你可以节省一些时间:
.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;
left: -20px;
border-top: 1px solid #ccc;
}
.tree li a{
display: inline-block;
border: 1px solid #ccc;
padding: 5px 10px;
text-decoration: none;
color: #666;
font-family: arial, verdana, tahoma;
font-size: 11px;
border-radius: 5px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
}
/*Remove connectors before root*/
.tree > ul > li::before, .tree > ul > li::after{
border: 0;
}
/*Remove connectors after last child*/
.tree li:last-child::before{
height: 30px;
}
/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after,
.tree li a:hover+ul li::before,
.tree li a:hover+ul::before,
.tree li a:hover+ul ul::before{
border-color: #94a0b4;
}

对于那些还在用CSS3搜索树的人来说,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>
<li>
<a href="#">Great Grand Child</a>
</li>
<li>
<a href="#">Great Grand Child</a>
</li>
<li>
<a href="#">Great Grand Child</a>
</li>
</ul>
</li>
<li><a href="#">Grand Child</a></li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
CSS
* {margin: 0; padding: 0;}
.tree ul {
padding-top: 20px; position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
.tree li {
float: left; text-align: center;
list-style-type: none;
position: relative;
padding: 20px 5px 0 5px;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
/*We will use ::before and ::after to draw the connectors*/
.tree li::before, .tree li::after{
content: '';
position: absolute; top: 0; right: 50%;
border-top: 1px solid #ccc;
width: 50%; height: 20px;
}
.tree li::after{
right: auto; left: 50%;
border-left: 1px solid #ccc;
}
/*We need to remove left-right connectors from elements without
any siblings*/
.tree li:only-child::after, .tree li:only-child::before {
display: none;
}
/*Remove space from the top of single children*/
.tree li:only-child{ padding-top: 0;}
/*Remove left connector from first child and
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{
border: 0 none;
}
/*Adding back the vertical connector to the last nodes*/
.tree li:last-child::before{
border-right: 1px solid #ccc;
border-radius: 0 5px 0 0;
-webkit-border-radius: 0 5px 0 0;
-moz-border-radius: 0 5px 0 0;
}
.tree li:first-child::after{
border-radius: 5px 0 0 0;
-webkit-border-radius: 5px 0 0 0;
-moz-border-radius: 5px 0 0 0;
}
/*Time to add downward connectors from parents*/
.tree ul ul::before{
content: '';
position: absolute; top: 0; left: 50%;
border-left: 1px solid #ccc;
width: 0; height: 20px;
}
.tree li a{
border: 1px solid #ccc;
padding: 5px 10px;
text-decoration: none;
color: #666;
font-family: arial, verdana, tahoma;
font-size: 11px;
display: inline-block;
border-radius: 5px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after,
.tree li a:hover+ul li::before,
.tree li a:hover+ul::before,
.tree li a:hover+ul ul::before{
border-color: #94a0b4;
}
PS:除了代码之外,我还喜欢网站展示它的方式……真的很创新。

如果有人想要Vitaliy Bychik的答案中的可扩展/可折叠版本的treeview,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();
});
});
