jQuery sortable - 设置哪些 div 包含在其父容器中

Question

我正在使用 jQuery 的 sortable 函数来允许用户重新排列 div 的顺序。当用户单击按钮时，会出现一个弹出 div。

目前，由于containment: 'parent'这一行，“已经存在的div”和“弹出的div”无法移出它们的容器

我如何允许弹出的 div 被移出它的容器，而不是已经存在的 div？

$("#click").on("click", function() {
  $("#sortable1").show();
});

$('#sortable1, #sortable2').sortable({
  axis: 'y',
  connectWith: '.first',
  containment: 'parent'
});

.container {
  position: absolute;
  margin: 0 auto;
  left: 0;
  right: 0;
  top: 13%;
  width: 85%;
}

div.div {
  border: 1px solid;
  margin-top: 7.5px;
  margin-bottom: 7.5px;
}

.popup {
  width: 50%;
  left: 0;
  right: 0;
  top: 20%;
  margin: 0 auto;
  z-index: 1;
  position: absolute;
  background: #fff;
  border: 1px solid;
}

<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<div id="sortable1" style="display: none;">
  <div class="popup">
    <h2>RED</h2>
    <p>When his peaceful life is threatened by a high-tech assassin, former black-ops agent Frank Moses reassembles his old team in a last ditch effort to survive and uncover his assailants.</p>
  </div>
</div>

<div class="container">

  <button id="click">Click me</button>
  <br>
  <br>

  <div id="sortable2" class="first">

    <div class="div">
      <h2>Deep Impact</h2>
      <p>Unless a comet can be destroyed before colliding with Earth, only those allowed into shelters will survive. Which people will survive?</p>
    </div>

    <div class="div">
      <h2>The Adjustment Bureau</h2>
      <p>The affair between a politician and a contemporary dancer is affected by mysterious forces keeping the lovers apart.</p>
    </div>

    <div class="div">
      <h2>Lord of the Flies</h2>
      <p>Stranded on an island, a group of schoolboys degenerate into savagery.</p>
    </div>
  </div>

</div>

这不会像您期望的那样工作。

看这里：https://jsfiddle.net/o0exme4f/2/

JavaScript

$(function() {
  $("#click").on("click", function() {
    $("#sortable1").show();
  });

  $("#sortable2").sortable({
    axis: 'y',
    containment: 'parent',
    items: "> div",
    update: function(e, ui) {},
    receive: function(e, ui) {
      console.log("Receiving item: ", ui.item);
      ui.item.attr("style", "").removeClass("popup").addClass("div");
    }
  });
  $("#sortable1").sortable({
    connectWith: '.first'
  });
});

收到新商品后，它会更新为与其他商品一​​样。某些样式导致它无法与其他元素很好地融合。
