Question

我在 gridview 中实施了选择下拉列表。 gridview位于div的框内。

我希望它能够在不受网格本身限制的情况下打开。我可以通过将overflow-x:visible !important;添加到网格样式来实现。

我希望网格也具有水平滚动功能。我将overflow:auto;添加到网格中。

但我不能两者兼顾。如果我执行第一个并使下拉列表可见，则网格会越过框并且滚动不再起作用。如果我做另一个，下拉后面的网格。

有两种方法吗？请随时使用以下示例向我展示。原谅并忽略代码的污秽。

<table cellspacing="0" id="ContentPlaceHolder1_grdInfo" style="width:100%;border-collapse:collapse;">
    <tbody>
        <tr style="height:50px;">

像这样：

https://jsfiddle.net/tqpxqose/2/

我更改的是我从div中删除了overflow-x并直接应用于select position:absolute

<select style="position:absolute" name="ctl00$ContentPlaceHolder1$grdInfo$ctl02$ddlItemHistory" id="ddlItemHistory" class="chzn-select chzn-done" style="display: none; background-color: rgb(128, 0, 128);">

水平滚动溢出
