html - 带有或不带有 Twitter Bootstrap 的嵌套侧边栏

Question

是否可以使用 twitter bootstrap 创建嵌套的左侧边栏？我检查了他们的教程，但找不到。我想制作一个带有一些列表的侧栏，每个列表都包含嵌套列表，默认情况下这些列表是隐藏的，当用户将鼠标悬停在列表上时，隐藏的选项应该变得可见。

<div class="span2">  
    <div class="well sidebar-nav">  
        <ul class="nav nav-list">  
            <li class="nav-header">Categories</li>  
            <li class="divider"></li>
            <li><a href="#">Books</a> 
                              <ul>
                                  <li><a href="#">Science Books</a></li>
                                  <li><a href="#">Computer Books</a></li>
                                  <li><a href="#">History Books</a></li>
                               </ul>
                            </li>  
            <li><a href="#">Electronics</a></li> 
                                <ul>
                                  <li><a href="#">TV</a></li>
                                  <li><a href="#">Freezer</a></li>
                                  <li><a href="#">Radio</a></li>
                                </ul> 
            <li><a href="#">Computer</a></li>
        </ul>  
    </div> 
</div>

可以用 twitter bootstarp 来做吗？如果没有其他解决方案？

谢谢

Answer 1

折叠您可以将折叠插件与 well+nav 类混合使用。示例
