Twitter-Bootstrap:并排的两个下拉切换按钮无法正常工作

Question

简介:我网站的一个部分需要一个小工具栏，其中包含两个并排的下拉菜单。我试图通过以下标记(简化)来实现这一点:

<div class="btn-group">
    <button class="btn btn-mini dropdown-toggle" data-toggle="dropdown">
        <span id="uniqueId">Text1</span> <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
        <li><a onclick="javascript:someFunction()">Item1</a></li>
        <li><a onclick="javascript:someFunction()">Item2</a></li>
        ...
    </ul>
    <button class="btn btn-mini dropdown-toggle" data-toggle="dropdown">
        <span id="uniqueId2">Text2</span> <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
        <li><a onclick="javascript:someOtherFunction()">Item1</a></li>
        <li><a onclick="javascript:someOtherFunction()">Item2</a></li>
        ...
    </ul>
</div>

我想要一个漂亮的两按钮工具栏，只有工具栏的外侧有圆角。

问题:

当我单击任一按钮时，两个按钮都显示为“已按下”，我无法从视觉上区分我刚刚单击了哪个按钮。所有其他功能都可以正常工作 - 即菜单显示正确且选项正确。

有没有办法让这些按钮分别改变它们的样式？

更新:

我确实知道通过将我的按钮分成两个 btn-group 很可能使这个工作正常进行s 或(如@Sherbrow 建议的那样)使用 div。 Bootstrap documentation还建议

Buttons with dropdowns must be individually wrapped in their own .btn-group within a .btn-toolbar for proper rendering.

我想知道 - 是否有可能以某种方式避免这种单独的包装并在单个 btn 组内有两个行为正确的下拉列表？

我认为我问的是非常非标准和无证的行为，如果没有人能提出一种方法，我会接受“那是不可能的”的答案。

Answer 1

您忘记了 .dropdown包装。

更新 2 : 忘记了一些组的代码。并发了gist (github)

更新 :做了更好的包装，和按钮的样式。这基本上是另一种按钮式样式，但没有 .btn 的包袱。类(class)。

<div class="btn-group">
    <div class="dropdown dropdown-btn">
        <div class="dropdown-toggle" data-toggle="dropdown">
            <span id="uniqueId">Text1</span><span class="caret"/>
        </div >
        <ul class="dropdown-menu">
            <li><a onclick="javascript:someFunction()">Item1</a></li>
            <li><a onclick="javascript:someFunction()">Item2</a></li>
            <!-- ... -->
        </ul>
    </div>
    <div class="dropdown dropdown-btn">
        <div class="dropdown-toggle" data-toggle="dropdown">
            <span id="uniqueId2">Text2</span><span class="caret"/>
        </div >
        <ul class="dropdown-menu">
            <li><a onclick="javascript:someOtherFunction()">Item1</a></li>
            <li><a onclick="javascript:someOtherFunction()">Item2</a></li>
            <!-- ... -->
        </ul>
    </div>
</div>

具有较大的 css 调整(buttons.less 和 button-groups.less 重用将 .btn 更改为 .dropdown-btn 从 here (github) ):
