我有一个带有下拉菜单的Bootstrap3导航栏.

我希望我的“注销”表单在该下拉列表中.它不是可见的形式,只是表单中的注销按钮.

我试过这个：

<div class="navbar-collapse collapse">
  <ul class="nav navbar-nav">
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button">Dropdown<span class="caret"></span></a>
      <ul class="dropdown-menu">

        <!-- this dropdown menu item looks right -->
        <li><a href="#">Foo</a></li>

        <!-- this dropdown menu item (a logout form) does not -->
        <li><form action="/logout" method="post"><button type="submit" class="btn btn-link navbar-btn navbar-link">Log off</button></form></li>

      </ul>
    </li>
  </ul>
</div>

但它没有正确的风格.

如何使其与正常下拉链接匹配？我希望我不需要手动调整css,并且有一个内置的方法来做到这一点？

解决方法

试试这个 Sample [UPDATED]

.btn-logout {
  width: 100%;
  padding: 3px 20px !important;
  text-align: left !important;
}
