Bootstrap 下拉列表 z-index 显示在模态窗口页脚下 [英] Bootstrap dropdownlist z-index displaying under modal window footer

问题描述

我在使用 bootstrap 时遇到了一些样式问题.

我有一个包含下拉菜单的小模态窗口.但是我似乎无法让下拉菜单显示在窗口的页脚上.

我使用了下拉菜单的 zindex 以确保它高于 windows，但没有运气.

谁能建议我应该改变什么?

HTML

<div class="modal-body"><p>请选择您正在工作的商店<div class="btn-group"><a class="btn dropdown-toggle" data-toggle="dropdown" href="#">Select<span class="caret"></span></a><ul class="下拉菜单">@foreach(模型中的 var 模型){<li><a href="#" class="store" data-id="@Html.DisplayFor(modelItem => model.StoreId)">@Html.DisplayFor(modelItem => model.StoreName)</＞}
</p>

<div class="modal-footer">

解决方案

您只需添加一个具有 z-index 作为属性的类，其属性高于模型框页脚.

要使 z-index 起作用，您还必须设置 position = relative、absolute 或 fixed.此外，将 z-index 设置为 5000 之类的内容可能会有所帮助.(模态的 z 指数可能高于 2000 年.

所以在你的 css 中我会添加这个:

.class-of-dropdown {位置:相对；z-索引:5000；}

.modal-body 类有一个 overflow-y: auto 属性.您可能需要将其更改为:

.modal-body {溢出-y:可见；}

I am having some styling problems with bootstrap.

I have a small modal window containing a dropdown. However I can't seem to get the dropdown to display over the footer of the window.

I have played with the zindex of the dropdown ensuring it was higher than the windows but no luck.

Can anyone suggest what I should be changing?

The html

<div class="modal hide fade" id="store-modal">
<div class="modal-header">
    <h3 id="reward-title">Select Store</h3>
</div>
<div class="modal-body">
    <p>
        Please select the store you are working from
            <div class="btn-group">
                <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">Select<span class="caret"></span></a>
                <ul class="dropdown-menu">
                    @foreach (var model in Model)
                    {
                        <li>
                            <a href="#" class="store" data-id="@Html.DisplayFor(modelItem => model.StoreId)">@Html.DisplayFor(modelItem => model.StoreName)</a>
                        </li>
                    }
                </ul>
            </div>

    </p>
</div>
<div class="modal-footer">
</div>

解决方案

You just add a class having z-index as attribute having higher than model box footer.

For z-index to work, you also have to set position = relative, absolute, or fixed. Also putting z-index something like 5000 might help. (the modal may have z index higher than the 2000's.

so in your css i would add this:

.class-of-dropdown {
    position: relative;
    z-index: 5000;
}

.modal-body class has a overflow-y: auto property. You might need to change this to:

.modal-body {
    overflow-y:visible;
}
