在 bootstrap 模态中显示 sumoselect

Question

我正在使用 sumoselect 进行选择，这个相加选择在 bootstrap 模态中。

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 css 下面的内容，那么它会起作用，但是如果我删除 css 的内容，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;
}

尝试从 sumoselect 选项容器中删除绝对位置 div。

在您的代码中添加以下 css 并享受！

<style type="text/css">

    .SumoSelect >.optWrapper
     {
       position:relative;        
     }
     .SumoSelect.open > .optWrapper
     {
        top:0;
     }

</style>
