如何保持可折叠项目的位置？

Question

我对可折叠卡片内的项目列表有疑问，发生这种情况：

我希望它看起来像这样：

是否可以使用 Bootstrap 的 Grid Layout 或 Flex Layout 做任何事情？

我的代码示例 (demo)

感谢任何可以提供帮助的人:)

Answer 1

将布局元素与内容元素结合起来并不是一个好主意。把它们分开就好了：

<div class="col-12 col-md-4">
  <div class="card">

您需要创建 3 列并将行放入其中

Answer 3

您可以只组成 3 列并将这些卡片堆放在每一列上，而不是将每张卡片放在自己的列上：

<div class="row">
    <div class="col-12 col-md-4">
        <div class="card">#1</div>
        <div class="card">#4</div>
    </div>
    <div class="col-12 col-md-4">
        <div class="card">#2</div>
        <div class="card">#5</div>
    </div>
    <div class="col-12 col-md-4">
        <div class="card">#3</div>
    </div>
</div>
