## zh-CN

我们提供了 `validateStatus` `help` `hasFeedback` 等属性，你可以不通过 Form 自己定义校验的时机和内容。

1. `validateStatus`: 校验状态，可选 'success', 'warning', 'error', 'validating'。
2. `hasFeedback`：用于给输入框添加反馈图标。
3. `help`：设置校验文案。

## en-US

We provide properties like `validateStatus` `help` `hasFeedback` to customize your own validate status and message, without using Form.

1. `validateStatus`: validate status of form components which could be 'success', 'warning', 'error', 'validating'.
2. `hasFeedback`: display feed icon of input control
3. `help`: display validate message.

```tsx
import { SmileOutlined } from '@ant-design/icons';
import {
  Cascader,
  DatePicker,
  Form,
  Input,
  InputNumber,
  Mentions,
  Select,
  TimePicker,
  TreeSelect,
} from 'antd';
import React from 'react';

const { Option } = Select;

const formItemLayout = {
  labelCol: {
    xs: { span: 24 },
    sm: { span: 6 },

  wrapperCol: {
    xs: { span: 24 },
    sm: { span: 14 },
  },
};
