【中文标题】在引导模式中显示 sumoselect【英文标题】：Display sumoselect in bootstrap modal 【发布时间】：2018-02-15 18:01:15 【问题描述】：我正在使用 sumoselect 进行选择，并且此 sumoselect 处于引导模式中。
但是当我打开下拉菜单时，会添加滚动条，我必须滚动才能看到下拉选项。
如果我删除下面的 css 那么它可以工作，但是如果我删除那个 css 那么它会影响我的整个应用程序。
$('.testselect10').SumoSelect();.modal-body
position: relative;
overflow-y: auto;
padding: 15px;

所以你不希望下拉菜单中有滚动条吗？ @ManishPatel，检查我更新的问题 【参考方案1】：只需添加仅对此模式有效的 css
$('.testselect10').SumoSelect();#myModal .modal-body
position: relative;
overflow-y: inherit;
padding: 15px;

我必须检查更改overflow后是否影响其他地方。【参考方案2】：
从.modal-body 类中删除overflow-y: auto。
$('.testselect10').SumoSelect();.modal-body
position: relative;
padding: 15px;

我知道如果我删除overflow-y:auto 它是有效的，但我不想删除它。
如果您可以使用jsfiddle.net 并向我们展示您的示例，因为解决方案就是@Ovidiu Unguru 所说的【参考方案3】：
尝试从 sumoselect 选项容器 div 中删除绝对位置。
在您的代码中添加下面的 css 并享受吧！
<style type="text/css">
.SumoSelect >.optWrapper
position:relative;
.SumoSelect.open > .optWrapper
top:0;
</style>
