javascript - 扩展 Accordion 列表项以保留在 flex 列中

Question

在下面的演示中，有两列包含列表项，当我单击列 #2 中的 #6 li 时，#5 li 跳转到第一列。有没有办法确保所有 3 个列表在单击时都留在第 2 列中？

$(function() {
  // (Optional) Active an item if it has the class "is-active"	
  $(".accordion > .accordion-item.is-active").children(".accordion-panel").slideDown();

  $(".accordion > .accordion-item").click(function() {
    // Cancel the siblings
    $(this).siblings(".accordion-item").removeClass("is-active").children(".accordion-panel").slideUp();
    // Toggle the item
    $(this).toggleClass("is-active").children(".accordion-panel").slideToggle("ease-out");
  });
});

ul {
  display: flex;
  flex-flow: wrap column;
  height: 200px; /*to change height to split ul list*/
  border: solid 1px red;
}

.accordion {
  list-style: none;
}

.accordion-thumb {
  margin: 0;
  padding: 5px;
  cursor: pointer;
  font-weight: normal;
}

.accordion-thumb::before {
  content: "";
  display: inline-block;
  height: 7px;
  width: 7px;
  -webkit-transition: -webkit-transform 0.2s ease-out;
  transition: -webkit-transform 0.2s ease-out;
  transition: transform 0.2s ease-out;
  transition: transform 0.2s ease-out, -webkit-transform 0.2s ease-out;
}

.accordion-panel {
  margin: -10px;
  display: none;
  margin-left: 12px;
  padding-bottom: 15px;
}

body {
  line-height: 1.5;
  margin: 0 auto;
  max-width: 500px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="accordion">
  <li class="accordion-item is-active">
    <h3 class="accordion-thumb">1.) list one</h3>
    <p class="accordion-panel">1111111111
    </p>
  </li>

  <li class="accordion-item">
    <h3 class="accordion-thumb">2.) list two</h3>
    <p class="accordion-panel">2222222222 </p>
  </li>

  <li class="accordion-item">
    <h3 class="accordion-thumb">3.) list three</h3>
    <p class="accordion-panel">3333333333
    </p>
  </li>

  <li class="accordion-item">
    <h3 class="accordion-thumb">4.) list four </h3>
    <p class="accordion-panel">4444444444 </p>
  </li>

  <li class="accordion-item">
    <h3 class="accordion-thumb">5.) list five</h3>
    <p class="accordion-panel">5555555555
    </p>
  </li>

  <li class="accordion-item">
    <h3 class="accordion-thumb">6.) list six</h3>
    <p class="accordion-panel">6666666666 </p>
  </li>

  <li class="accordion-item">
    <h3 class="accordion-thumb">7.) list seven</h3>
    <p class="accordion-panel">7777777777
    </p>
  </li>
</ul>

Answer 1

这是在 css 中使用 Column-count 的解决方案

demo

它确实以不同的方式解决了你的问题

我已经从你的示例代码中更改了这个

添加了一个<li>在第四和第五之间<li>

<li class="column-break">&nbsp;</li>

将 UL 的 css 更改为:

    ul {
  height: 200px;
  border: solid 1px red;
  column-count: 2;
}

为 <li> 添加了 CSS与类“分栏”

.column-break {
  break-after: column;
}
