Bootstrap的下拉菜单被数据表隐藏

我正在使用Twitter Bootstrap为DataTables网格中的每一行创建一个带有下拉菜单的按钮,但DataTables中的数据容器使用的是“overflow:隐藏”什么是使下拉菜单被削减。
我不能就这么切换到“溢出:自动”,因为这将导致出现不必要的垂直滚动条。
这是一个JSFiddle

<table cellpadding="0" cellspacing="0" border="0" class="pretty" id="example"></table>

/* API method to get paging information */
$.fn.dataTableExt.oApi.fnPagingInfo = function (oSettings) {
    return {
        "iStart": oSettings._iDisplayStart,
            "iEnd": oSettings.fnDisplayEnd(),
            "iLength": oSettings._iDisplayLength,
            "iTotal": oSettings.fnRecordsTotal(),

我遇到了同样的问题!解决了移除component.css中的溢出属性

.table-scrollable {
  width: 100%;
/*  overflow-x: auto;
  overflow-y: hidden;*/
  border: 1px solid #dddddd;
  margin: 10px 0 !important;
}

或者添加到custom.css(引导后调用)

.table-scrollable { 
    overflow-x: visible; 
    overflow-y: visible; 
}

这对我很有效:数据表+固定标头+标头中的引导下拉列表

.dataTables_scrollHead{
    overflow: visible !important;
}

添加到自定义css后的所有其他

听了我们的评论我知道你想要什么了
您有一个<div>元素,其中包含overflow:auto,并且您希望该<div>(菜单所在的<ul>)中的某个元素从溢出规则中“escape”,并且显示为浮动,从而覆盖其祖先的溢出规则。
但恐怕这是不可能的你能做的最接近的事是:

  • 使用javascript创建<ul>,其菜单位于<div>外部,并带有overflow:auto,然后使用绝对位置设置其位置,或者
  • 使用javascript在下拉菜单激活后自动滚动底部,方法是在最后一个下拉菜单中添加类似事件监听器的东西。

第二个选项似乎更优雅,更少“黑客”。(我个人会忽略这个问题,但如果我必须选择,我会选择第二个选项)

对我起作用的是将Bootstrap下拉菜单的位置调整为fixed,并将菜单移动到屏幕的特定部分。
而且它适用于移动的视图,因为它是相对于窗口的。

table .dropdown-menu {
    position: fixed !important;
    top: 50% !important;
    left: 92% !important;
    transform: translate(-92%, -50%) !important;
}

这样,您就可以保留DataTablesscroller扩展、scrollXscrollY属性的行为。

快速简单的解决方法是定义div.dataTables_scrollHead:hover { overflow: hidden !important },然后如果问题仍然存在,那么另一个对我有效的快速解决方案是定义高度滚动头部和边缘顶部滚动身体,例如:

div.dataTables_scrollHead {
            height: 250px;
        }
div.dataTables_scrollBody {
        margin-top: -190px;
    }

这应该解决了问题。
