我使用Bootstrap 5示例来水平放置标签和输入字段。
我强制错误类测试错误的位置。
无论我尝试了什么，错误都没有显示。该字段有红色边框和错误图标，但没有显示错误消息。
如果字段不是这样水平的，则会显示错误：

<div class="col-md-6">
     <label for="password" class="form-label">Password</label>
     <input type="text" class="form-control is-invalid" id="password" aria-describedby="passwordError">
     <div id="passwordError" class="invalid-feedback">
          <strong>Error here</strong>
     </div>
</div>

那么你如何显示水平样式的错误呢？

      <div class="col-auto">
        <span id="passwordHelp" class="form-text">
        Must be 8-20 characters long.
      </span>
      </div>
      <div id="passwordError" class="invalid-feedback" role="alert">
        <strong>Error here</strong>
      </div>
    </div>
  </form>
</div>
