css - Bootstrap 中不能出现 "pull-right"图标字形

Question

我想在下拉菜单中拉出右图标字形，如下所示

<div class="navbar">
  <div class="navbar-inner">
    <ul class="nav">
      <li class="dropdown">
        <a data-toggle="dropdown" class="dropdown-toggle" href="#">Dropdown <b class="caret"></b></a>
        <ul class="dropdown-menu">
          <li>
            <a href="#">2-level Dropdown <i class="icon-arrow-right pull-right"></i></a>
            <ul class="dropdown-menu sub-menu">
              <li><a href="#">Action</a></li>
              <li><a href="#">Another action</a></li>
              <li><a href="#">Something else here</a></li>
            </ul>
          </li>
          <li><a href="#">Another action</a></li>
          <li class="divider"></li>
          <li><a href="#">One more separated link</a></li>
        </ul>
      </li>
    </ul>
  </div>
</div>

但是当我在 FireFox(Chrome 和 IE 都可以)上运行这段代码时，“icon-arrow-right”和“2-level Dropdown”不是同一行。我该如何解决？
