简介：我网站的其中一个部分需要一个小工具栏，并排有两个下拉菜单。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>
我想在工具栏的外侧看到一个带有圆角的漂亮的双按钮工具栏。
问题：
当我点击任一按钮时，两个按钮都显示为“按下”，我无法在视觉上区分出我刚刚点击的按钮。所有其他功能都正常工作 - 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
我知道通过使用div将我的按钮分成两个btn-group或（如@Sherbrow建议的那样），可以很好地实现这一点。 Bootstrap documentation也建议
带有下拉列表的按钮必须单独包装在.btn工具栏中的.btn-group中，以便正确呈现。
我想知道 - 是否有可能以某种方式避免这种个别包装并在单个btn组中有两个正常表现的下拉？
我认为我在问非常非标准和无证的行为，如果没有人能提出办法，我会接受“这是不可能的”答案。
答案 0 :(得分：11)
您忘记了.dropdown包装。
更新2 ：忘记了一些群组代码。并制作了gist (github)
更新：做了更好的包装，并且像按钮一样造型。这基本上是另一种按钮式样式，但没有.btn类的包袱。
<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>
有一个大的css调整（buttons.less和button-groups.less重用.btn从here (github)改为.dropdown-btn）：

或者您可以将一个CSS类添加到btn-group div并改为：

HTML：
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<div class="pull-left">
<div class="btn-group btn-group-merge">
<a class="btn" href="#" data-toggle="dropdown"><i class="icon icon-certificate"></i></a>
<ul class="dropdown-menu">
<li><a href="#">One</a></li>
<li><a href="#">Two</a></li>
<li><a href="#">Three</a></li>
</ul>
</div>
<div class="btn-group btn-group-merge">
<a class="btn" href="#" data-toggle="dropdown"><i class="icon icon-comment"></i></a>
<ul class="dropdown-menu">
<li><a href="#">A B C</a></li>
<li><a href="#">D E F</a></li>
<li><a href="#">G H I</a></li>
</ul>
</div>
</div>
</div>
</div>
</div>
CSS：
.navbar-fixed-top .btn-group-merge {
margin-left : -5px;
}
.navbar-fixed-top .btn-group-merge:first-child {
margin-left : 0;
}
.navbar-fixed-top .btn-group-merge .btn {
border-radius: 0 4px 4px 0;
}
.navbar-fixed-top .btn-group-merge:first-child .btn {
border-radius: 4px 0 0 4px;
}
这将适用于按钮组中的任意数量的按钮，但只会正确呈现第一个和最后一个按钮。您可以使用一些CSS-fu来修复它，但它不会在IE＆lt; 10上呈现。

将每个集合添加到自己的btn-group div中对我来说很成功。现在，这两个下拉菜单中的每一个都显示在同一行上，并正确打开了它们的相关菜单选项。只要确保每个集合的ID是唯一的即可。 （SP 2016 OnPrem）
<div class="btn-group">
<button class="btn btn-primary dropdown-toggle" id="TranslatorActions" type="button" data-toggle="dropdown" style="display:none"> Translator Actions <span class="caret"></span></button>
<ul id="TranslatorActionsMenu" class="dropdown-menu dropdown-menu-right" role="menu" aria-labelledby="TranslatorActions">
<!–– Drop downs are added via script as needed -->
</ul>
</div>
<div class="btn-group">
<button class="btn btn-primary dropdown-toggle" id="AdminActions" type="button" data-toggle="dropdown" style="display:none">Admin Actions <span class="caret"></span></button>
<ul id="AdminActionsMenu" class="dropdown-menu dropdown-menu-right" role="menu" aria-labelledby="AdminActions">
<li><a role="menuitem" tabindex="-1" href="javascript:void(0);" onclick="OpenAdminForm();">Open Admin Form</a></li>
</ul>
</div>
