使CSS Flex元素忽略容器元素

Question

我正在努力创建类似于Chosen的组件，但是我遇到了flex和wrap的问题。要点是，伪文本框中的每个“筹码”都必须位于一个不包含实际文本输入的容器中，但是我需要将这些筹码作为与相同的基础视为flex元素input。

我的HTML结构如下所示：

<div class="box">
  <div class="chipContainer">
    <div class="chip">Chip1</div>
    <div class="chip">Chip2</div>
    <div class="chip">Chip3</div>
    <div class="chip">Chip4</div>
  </div>
  <input class="textbox" type="text">
</div>

这个Plunker示例更加完整，其样式与我目前正在使用的样式大致相同。

<div class="box">
  <div class="chipContainer">
    <div class="chip">Chip1</div>
    <div class="chip">Chip2</div>
    <div class="chip">Chip3</div>
    <div class="chip">Chip4</div>
  </div>
  <input class="textbox" type="text">
</div>

.box {
  background: #fff;
  border: 1px solid #ccc;
  width: 500px;
  overflow: auto;
  padding: 2px;
  display: flex;
  flex-wrap: wrap;
}
.chip {
  display: inline-block;
  border: 1px solid #ccc;
  background: #eee;
  padding: 2px;
  margin-right: 1px;
  flex: auto;
}
.textbox {
  border: none;
  background: #fdd;
  font-size: 18px;
  flex: auto;
}
.textbox:focus {
  outline: none;
}
.chipContainer {
  display: inline;
}

如您所见，在将足够多的芯片添加到.box容器之后，.chipContainer它们将开始包裹它们，但.chipContainer仍然是一个块元素，并将其input完全向下推到新的一行。

这个Plunker示例演示了我的目标。一旦.chipContainer删除，就可以很容易地实现布局，但是这是组件结构中相当重要的元素，如果可能的话，我宁愿解决而不删除它。

<div class="box">
  <div class="chipContainer">
    <div class="chip">Chip1</div>
    <div class="chip">Chip2</div>
    <div class="chip">Chip3</div>
    <div class="chip">Chip4</div>
  </div>
  <input class="textbox" type="text">
</div>
<br>
<div class="box">
  <div class="chipContainer">
    <div class="chip">Chip1</div>
    <div class="chip">Chip2</div>
    <div class="chip">Chip3</div>
    <div class="chip">Chip4</div>
    <div class="chip">Chip5</div>
    <div class="chip">Chip6</div>
    <div class="chip">Chip7</div>
    <div class="chip">Chip8</div>
    <div class="chip">Chip9</div>
    <div class="chip">Chip10</div>
    <div class="chip">Chip11</div>
  </div>
  <input class="textbox" type="text">
</div>

.box {
  background: #fff;
  border: 1px solid #ccc;
  width: 500px;
  overflow: auto;
  padding: 2px;
  display: flex;
  flex-wrap: wrap;
}
.chip {
  display: inline-block;
  border: 1px solid #ccc;
  background: #eee;
  padding: 2px;
  margin-right: 1px;
  flex: auto;
  min-width: 50px;
  max-width: 60px;
}
.textbox {
  border: none;
  background: #fdd;
  font-size: 18px;
  flex: auto;
  min-width: 250px;
}
.textbox:focus {
  outline: none;
}
.chipContainer {
  display: inline;
}

Answer 1

Display Module Level 3 instroduces display: contents:

The element itself does not generate any boxes, but its children and pseudo-elements still generate boxes as normal. For the purposes of box generation and layout, the element must be treated as if it had been replaced with its children and pseudo-elements in the document tree.

So you just need

.chipContainer {
  display: contents;
}

.box {
  background: #fff;
  border: 1px solid #ccc;
  width: 500px;
  overflow: auto;
  padding: 2px;
  display: flex;
  flex-wrap: wrap;
}
.chip {
  display: inline-block;
  border: 1px solid #ccc;
  background: #eee;
  padding: 2px;
  margin-right: 1px;
  flex: auto;
  min-width: 50px;
  max-width: 60px;
}
.textbox {
  border: none;
  background: #fdd;
  font-size: 18px;
  flex: auto;
}
.textbox:focus {
  outline: none;
}
.chipContainer {
  display: contents;
}

<div class="box">
  <div class="chipContainer">
    <div class="chip">Chip1</div>
    <div class="chip">Chip2</div>
    <div class="chip">Chip3</div>
    <div class="chip">Chip4</div>
  </div>
  <input class="textbox" type="text">
</div>
<br>
<div class="box">
  <div class="chipContainer">
    <div class="chip">Chip1</div>
    <div class="chip">Chip2</div>
    <div class="chip">Chip3</div>
    <div class="chip">Chip4</div>
    <div class="chip">Chip5</div>
    <div class="chip">Chip6</div>
    <div class="chip">Chip7</div>
    <div class="chip">Chip8</div>
    <div class="chip">Chip9</div>
    <div class="chip">Chip10</div>
    <div class="chip">Chip11</div>
  </div>
  <input class="textbox" type="text">
</div>

但是，请注意，它尚未得到广泛支持。
