在twitter bootstrap bs-docs-sidebar下面添加其他项目

Question

所以我现在尝试做的是在bs-docs-sidebar下面添加一些用于twitter bootstrap的东西。我目前正在使用此代码

<div class="row-fluid">
<div class="span3 bs-docs-sidebar">
<div class="row-fluid">
     <ul class="nav nav-list bs-docs-sidenav affix">
        <li><a href="#typography"><i class="icon-chevron-right"></i>item 1</a></li>
        <li><a href="#code"><i class="icon-chevron-right"></i> item 2</a></li>
        <li><a href="#tables"><i class="icon-chevron-right disabled"></i> Item 3</a></li>
        <li><a id="contribute" href="#forms"><i class="icon-chevron-right"></i> item 4</a>          
        <li><a id="contribute" href="#buttons"><i class="icon-chevron-right"></i> item </li> 5</a></li>
    </ul>
    <div class="well affix">
        <h4>Big Heading</h4>
        <div class="btn-group btn-block">
            <button type="button" class="btn btn-warning">option 1</button>
            <button type="button" class="btn btn-warning">option 2</button>
            <button type="button" class="btn btn-warning">option 3</button>
        </div>
        <h4 class="pagination-centered">Or</h4>
        <button class="btn btn-block btn-primary">Alternative</button>
    </div>
</div>

但井的位置，不在导航菜单下方，它停留在页面底部，并因为井内容似乎将其推出范围而截止，有没有办法贴上改为导航菜单的底部？
