使用带有浮动标签的输入组时不显示引导验证反馈

Answer 1

反馈必须与输入元素位于同一div上：

<div class="input-group has-validation">
    <div class="form-floating">
        <input name="token" placeholder="Enter your admin token" type="password" class="form-control is-valid"
        value="some token" />
        <label>Access Token</label>
        <div class="valid-feedback">Looks good!</div>
    </div>
    <button type="submit" class="btn btn-success">Log in</button>
</div>
