javascript - 在输入组中引导 5 个 float 标签

Question

我想一起使用 Bootstrap 的“ float 标签”和“输入组”组件。
我遇到的麻烦是当输入聚焦时标签是隐藏的。
在下面的代码示例中，我有以下场景:

两个组件(请参阅单击输入时标签消失)。

仅 float 标签

有谁知道使这些组件协同工作的方法？

<div class="form-floating input-group mb-3">
    <input type="text" class="form-control" name="code1" placeholder="Code 1">
    <label for="code1">Code 1</label>
    <span class="input-group-text"><i class="fas fa-times"></i></span>
</div>

<div class="form-floating mb-3">
    <input type="text" class="form-control" name="code4" placeholder="Code 4">
    <label for="code4">Code 4</label>
</div>

将 float 标签放在另一个 input-group 中分区。

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.0/dist/css/bootstrap.min.css" rel="stylesheet"/>

<div class="input-group mb-3">
  <div class="form-floating flex-grow-1">
      <input type="text" class="form-control" name="code1" placeholder="Code 1">
      <label for="code1">Code 1</label>
  </div>
  <span class="input-group-text"><i class="fas fa-times"></i></span>
</div>

更新 : 自 Bootstrap 5.2 起，flex-grow-1不再需要并且自动处理边界舍入。

<div class="input-group mb-3">
  <div class="form-floating">
      <input type="text" class="form-control" name="code1" placeholder="Code 1">
      <label for="code1">Code 1</label>
  </div>
  <span class="input-group-text"><i class="fas fa-times"></i></span>
</div>
