如何自定义引导侧边栏/sidenav？

I need to make use of Twitter Bootstrap Sidebar for creating a menu in my web application.(Highlighted in red).

To create a menu as shown below.

顶部项目有一个下拉菜单，如法师所示。菜单中的下一个项目应该位于此下方。但这就是我使用 css 时得到的结果。

菜单项与其他项重叠。

这里是引导程序代码：

<div class="span3 bs-docs-sidebar">
    <ul class="nav nav-list bs-docs-sidenav affix">
      <li class="active"><a href="#dropdowns"><i class="icon-chevron-right"></i> Dropdowns</a></li>
      <li class=""><a href="#buttonGroups"><i class="icon-chevron-right"></i> Button groups</a></li>
      <li><a href="#buttonDropdowns"><i class="icon-chevron-right"></i> Button dropdowns</a></li>
      <li><a href="#navs"><i class="icon-chevron-right"></i> Navs</a></li>
      <li><a href="#navbar"><i class="icon-chevron-right"></i> Navbar</a></li>
      <li><a href="#breadcrumbs"><i class="icon-chevron-right"></i> Breadcrumbs</a></li>
      <li><a href="#pagination"><i class="icon-chevron-right"></i> Pagination</a></li>
      <li><a href="#labels-badges"><i class="icon-chevron-right"></i> Labels and badges</a></li>
      <li><a href="#typography"><i class="icon-chevron-right"></i> Typography</a></li>
      <li><a href="#thumbnails"><i class="icon-chevron-right"></i> Thumbnails</a></li>
      <li><a href="#alerts"><i class="icon-chevron-right"></i> Alerts</a></li>
      <li><a href="#progress"><i class="icon-chevron-right"></i> Progress bars</a></li>
      <li><a href="#media"><i class="icon-chevron-right"></i> Media object</a></li>
      <li><a href="#misc"><i class="icon-chevron-right"></i> Misc</a></li>
    </ul>
  </div>

Here is my code:

 <div class="span3 bs-docs-sidebar">
    <ul class="nav nav-list bs-docs-sidenav affix">
        <li> <a class="dropdown-toggle" data-toggle="dropdown" href="#">
                <i class="icon-user"></i>dany
                <span class="caret"></span>
            </a>
            <ul class="dropdown-menu">
                <li><a id="logout" href="#">Sign Out</a></li>
            </ul>
        </li>
    </ul>
</div>
<div class="span3 bs-docs-sidebar">
    <ul class="nav nav-list bs-docs-sidenav `affix`">
        <li><a href="#approval" id="approval"></i>Approval Requests</a></li>
        <li><a href="#setting" id="setting"></i>Settings</a></li>
    </ul>
</div>

bootstrap中的css类设置的位置是bs-docs-sidenav and affix我相信。 twitter bootstrap 的 docs.css 的 css 是this http://twitter.github.com/bootstrap/assets/css/docs.css

请任何人帮忙尽快解决这个问题。

您正在使用span3在您的两个菜单上。这意味着第二个菜单将放置在右侧的下一个网格上，而不是第一个菜单的下方。

我相信你应该这样开始——

<div class="span3 bs-docs-sidebar">
    <ul class="nav nav-list bs-docs-sidenav affix">
        <li> <a class="dropdown-toggle" data-toggle="dropdown" href="#">
                <i class="icon-user"></i>dany
                <span class="caret"></span>
            </a>
            <ul class="dropdown-menu">
                <li><a id="logout" href="#">Sign Out</a></li>
            </ul>
        </li>
    </ul>

    <ul class="nav nav-list bs-docs-sidenav affix">
        <li><a href="#approval" id="approval"></i>Approval Requests</a></li>
        <li><a href="#setting" id="setting"></i>Settings</a></li>
    </ul>
</div>

现在在第二个菜单上应用一些 CSS，例如

<ul class="nav nav-list bs-docs-sidenav affix" style="top: 200px;">
