我正在使用Twitter Bootstrap为DataTables网格中的每一行创建一个带DropDown菜单的按钮,但DataTables的数据容器正在使用“overflow:hidden”使DropDown被切割。
我不能只切换到“overflow:auto”,因为这会导致出现不必要的垂直滚动条。
这是JSFiddle

我遇到了同样的问题!已解决删除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(在bootstrap之后调用)
.table-scrollable {
overflow-x: visible;
overflow-y: visible;
}
答案 1 :(得分:4)
这对我有用:数据表+固定标题+标题中的引导下拉列表
.dataTables_scrollHead{
overflow: visible !important;
}
在所有其他人之后添加到自定义css
答案 2 :(得分:2)
好的,在我们发表评论之后,我意识到了你想要的东西:
您有一个<div>
元素与overflow:auto
,并且您希望<div>
(菜单所在的<ul>
)内的元素为“溢出“溢出规则,显示浮动,覆盖其祖先的溢出规则。
但我担心不可能。你能做的最接近的事情是:
<ul>
菜单在之外的<div>
和overflow:auto
,然后使用position absolute来设置它应该去的位置,或第二种选择似乎更优雅,更少“黑客”。 (就个人而言,我会忽略这个问题,但如果我必须选择,我会选择第二个选项)
答案 3 :(得分:1)
对我有用的是将 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。
它适用于移动视图,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;
}
通过这种方式,您可以保留 scroller
扩展名、scrollX
和 scrollY
属性的行为。
答案 4 :(得分:0)
覆盖.dataTables_scrollHead选择器的DataTable css规则为我工作
.dataTables_scrollHead{
position: static !important;
}
