我正在使用Bootstrap 3并尝试在面板标题的右侧添加一个下拉菜单。我的按钮位于float:right
,但下拉菜单不再呈现连接到按钮。我认为浮动正在打破与下拉菜单的链接。
我尝试添加float:right
并删除position:absolute
(覆盖到position:initial
)我可以在按钮旁边显示下拉列表,但最终会包含在{{1}中div,它将面板标题扩展为菜单大小。
我能做些什么吗?

您需要将dropdown
按钮放在btn-group
标记内:请参阅Docs
工作示例代码段。
.panel-collapsable .panel-heading h4:after {
font-family: 'Glyphicons Halflings';
content: "\e114";
float: right;
color: white;
margin-right: 5px;
cursor: pointer;
}
.panel-collapsable .collapsed h4:after {
content: "\e080";
}
.panel-heading .btn-group {
float: right;
}

尝试将此CSS样式添加到下拉列表中:
.panel-heading .dropdown-menu {
right: 31px;
top: 42px;
left: initial;
}
绝对定位与父面板有关,因此您只需根据自己的喜好调整顶部/右侧/左侧/底部设置。
