如何維護可折疊項目 position？

Question

我對可折疊卡片中的項目列表有疑問，發生了這種情況：

我希望它看起來像這樣：

是否可以使用 Bootstrap 的網格布局或 Flex 布局來按需進行？

您需要創建 3 列並將行放在其中

Answer 2

你可以只組成 3 列並將這些卡片堆放在每一列上，而不是將每張卡片放在自己的列中：

<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>

Answer 3

將布局元素與內容元素結合起來很少是個好主意。 將它們分開，一切都很好：

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