| preserve | Keep field value even when field removed | boolean | true | 4.4.0 |
| requiredMark | Required mark style. Can use required mark or optional mark. You can not config to single Form.Item since this is a Form level config | boolean \| `optional` \| ((label: ReactNode, info: { required: boolean }) => ReactNode) | true | `renderProps`: 5.9.0 |
| scrollToFirstError | Auto scroll to first failed field when submit | boolean \| [Options](https://github.com/stipsan/scroll-into-view-if-needed/tree/ece40bd9143f48caf4b99503425ecb16b0ad8249#options) | false | |
| size | Set field component size (antd components only) | `small` \| `middle` \| `large` | - | |
| validateMessages | Validation prompt template, description [see below](#validatemessages) | [ValidateMessages](https://github.com/ant-design/ant-design/blob/6234509d18bac1ac60fbb3f92a5b2c6a6361295a/components/locale/en_US.ts#L88-L134) | - | |
| validateTrigger | Config field validate trigger | string \| string\[] | `onChange` | 4.3.0 |
| wrapperCol | The layout for input controls, same as `labelCol` | [object](/components/grid/#col) | - | |
| onFieldsChange | Trigger when field updated | function(changedFields, allFields) | - | |

### validateMessages
Form provides [default verification error messages](https://github.com/ant-design/ant-design/blob/6234509d18bac1ac60fbb3f92a5b2c6a6361295a/components/locale/en_US.ts#L88-L134). You can modify the template by configuring `validateMessages` property. A common usage is to configure localization:
2016-07-31 09:53:51 +08:00
```jsx
const validateMessages = {
required: "'${name}' is required!",
// ...
};
2016-07-31 09:53:51 +08:00
<Form validateMessages={validateMessages} />;
```
Besides, [ConfigProvider](/components/config-provider/) also provides a global configuration scheme that allows for uniform configuration error notification templates:
2016-07-31 09:53:51 +08:00
```jsx
const validateMessages = {
required: "'${name}' is Required!",
// ...
};
2016-07-31 09:53:51 +08:00
<ConfigProvider form={{ validateMessages }}>
<Form />
</ConfigProvider>;
2016-07-31 09:53:51 +08:00
```
## Form.Item
2016-07-31 09:53:51 +08:00
Form field component for data bidirectional binding, validation, layout, and so on.
2020-04-07 20:43:19 +08:00
| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |
| colon | Used with `label`, whether to display `:` after label text. | boolean | true | |
| dependencies | Set the dependency field. See [below](#dependencies) | [NamePath](#namepath)\[] | - | |
2020-10-09 10:08:52 +08:00
| extra | The extra prompt message. It is similar to help. Usage example: to display error message and prompt message at the same time | ReactNode | - | |
| getValueFromEvent | Specify how to get value from event or other onChange arguments | (..args: any\[]) => any | - | |
| getValueProps | Additional props with sub component | (value: any) => any | - | 4.2.0 |
2020-04-07 20:43:19 +08:00
| hasFeedback | Used with `validateStatus`, this option specifies the validation status icon. Recommended to be used only with `Input` | boolean | false | |
2020-10-09 10:08:52 +08:00
| help | The prompt message. If not provided, the prompt message will be generated by the validation rule. | ReactNode | - | |
| hidden | Whether to hide Form.Item (still collect and validate value) | boolean | false | 4.4.0 |
2020-04-07 20:43:19 +08:00
| htmlFor | Set sub label `htmlFor` | string | - | |
| initialValue | Config sub default value. Form `initialValues` get higher priority when conflict | string | - | 4.2.0 |
2020-10-09 10:08:52 +08:00
| label | Label text | ReactNode | - | |
| labelAlign | The text align of label | `left` \| `right` | `right` | |
| labelCol | The layout of label. You can set `span` `offset` to something like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` same as with `<Col>`. You can set `labelCol` on Form which will not affect nest Item. If both exists, use Item first | [object](/components/grid/#col) | - | |
| messageVariables | The default validate field info | Record&lt;string, string> | - | 4.7.0 |
| name | Field name, support array | [NamePath](#namepath) | - | |
| normalize | Normalize value from component value before passing to Form instance. Do not support async | (value, prevValue, prevValues) => any | - | |
| noStyle | No style for `true`, used as a pure field control | boolean | false | |
| preserve | Keep field value even when field removed | boolean | true | 4.4.0 |
| required | Display required style. It will be generated by the validation rule | boolean | false | |
| rules | Rules for field validation. Click [here](#components-form-demo-basic) to see an example | [Rule](#rule)\[] | - | |
| shouldUpdate | Custom field update logic. See [below](#shouldupdate) | boolean \| (prevValue, curValue) => boolean | false | |
| tooltip | Config tooltip info | ReactNode \| [TooltipProps & { icon: ReactNode }](/components/tooltip#api) | - | 4.7.0 |
| trigger | When to collect the value of children node. Click [here](#components-form-demo-customized-form-controls) to see an example | string | `onChange` | |
| validateFirst | Whether stop validate on first rule of error for this field. Will parallel validate when `parallel` configured | boolean \| `parallel` | false | `parallel`: 4.5.0 |
| validateStatus | The validation status. If not provided, it will be generated by validation rule. options: `success` `warning` `error` `validating` | string | - | |
| validateTrigger | When to validate the value of children node | string \| string\[] | `onChange` | |
| valuePropName | Props of children node, for example, the prop of Switch is 'checked'. This prop is an encapsulation of `getValueProps`, which will be invalid after customizing `getValueProps` | string | `value` | |
| wrapperCol | The layout for input controls, same as `labelCol`. You can set `wrapperCol` on Form which will not affect nest Item. If both exists, use Item first | [object](/components/grid/#col) | - | |
After wrapped by `Form.Item` with `name` property, `value`(or other property defined by `valuePropName`) `onChange`(or other property defined by `trigger`) props will be added to form controls, the flow of form data will be handled by Form which will cause:
1. You shouldn't use `onChange` on each form control to **collect data**(use `onValuesChange` of Form), but you can still listen to `onChange`.
2020-12-03 13:45:27 +08:00
2. You cannot set value for each form control via `value` or `defaultValue` prop, you should set default value with `initialValues` of Form. Note that `initialValues` cannot be updated by `setState` dynamically, you should use `setFieldsValue` in that situation.
3. You shouldn't call `setState` manually, please use `form.setFieldsValue` to change value programmatically.
### dependencies
Used when there are dependencies between fields. If a field has the `dependencies` prop, this field will automatically trigger updates and validations when upstream is updated. A common scenario is a user registration form with "password" and "confirm password" fields. The "Confirm Password" validation depends on the "Password" field. After setting `dependencies`, the "Password" field update will re-trigger the validation of "Check Password". You can refer [examples](#components-form-demo-dependencies).
`dependencies` shouldn't be used together with `shouldUpdate`, since it may result in conflicting update logic.
### shouldUpdate
Form updates only the modified field-related components for performance optimization purposes by incremental update. In most cases, you only need to write code or do validation with the [`dependencies`](#dependencies) property. In some specific cases, such as when a new field option appears with a field value changed, or you just want to keep some area updating by form update, you can modify the update logic of Form.Item via the `shouldUpdate`.
When `shouldUpdate` is `true`, any Form update will cause the Form.Item to be re-rendered. This is very helpful for custom rendering some areas. It should be noted that the child component should be returned in a function, otherwise `shouldUpdate` won't behave correctly:
related issue: [#34500](https://github.com/ant-design/ant-design/issues/34500)
```jsx
<Form.Item shouldUpdate>
{() => {
return <pre>{JSON.stringify(form.getFieldsValue(), null, 2)}</pre>;
}}
</Form.Item>
```

You can ref [example](#components-form-demo-horizontal-login) to see detail.
2016-07-31 09:53:51 +08:00
When `shouldUpdate` is a function, it will be called by form values update. Providing original values and current value to compare. This is very helpful for rendering additional fields based on values:
2018-09-12 22:16:53 +08:00
```jsx
<Form.Item shouldUpdate={(prevValues, curValues) => prevValues.additional !== curValues.additional}>
{() => {
return (
<Form.Item name="other">
<Input />
</Form.Item>
);
}}
</Form.Item>
2018-09-12 22:16:53 +08:00
```
You can ref [example](#components-form-demo-control-hooks) to see detail.
### messageVariables
You can modify the default verification information of Form.Item through `messageVariables`.
```jsx
<Form>
<Form.Item
messageVariables={{ another: 'good' }}
label="user"
rules={[{ required: true, message: '${another} is required' }]}
>
<Input />
</Form.Item>
<Form.Item
messageVariables={{ label: 'good' }}
label={<span>user</span>}
rules={[{ required: true, message: '${label} is required' }]}
>
<Input />
</Form.Item>
</Form>
```
## Form.List
Provides array management for fields.
| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |
| children | Render function | (fields: Field\[], operation: { add, remove, move }, meta: { errors }) => React.ReactNode | - | |
| initialValue | Config sub default value. Form `initialValues` get higher priority when conflict | any\[] | - | 4.9.0 |
2023-07-27 09:56:05 +08:00
| name | Field name, support array. List is also a field, so it will return all the values by `getFieldsValue`. You can change this logic by [config](#getfieldsvalue) | [NamePath](#namepath) | - | |
| rules | Validate rules, only support customize validator. Should work with [ErrorList](#formerrorlist) | { validator, message }\[] | - | 4.7.0 |
```tsx
<Form.List>
{(fields) => (
<div>
{fields.map((field) => (
<Form.Item {...field}>
<Input />
</Form.Item>
))}
</div>
)}
</Form.List>
```
Note: You should not configure Form.Item `initialValue` under Form.List. It always should be configured by Form.List `initialValue` or Form `initialValues`.
## operation
Some operator functions in render form of Form.List.
| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |
| add | add form item | (defaultValue?: any, insertIndex?: number) => void | insertIndex | 4.6.0 |
| move | move form item | (from: number, to: number) => void | - | |
| remove | remove form item | (index: number \| number\[]) => void | number\[] | 4.5.0 |
## Form.ErrorList
New in 4.7.0. Show error messages, should only work with `rules` of Form.List. See [example](#components-form-demo-dynamic-form-item).
2021-04-12 17:48:28 +08:00
| Property | Description | Type | Default |
| -------- | ----------- | ------------ | ------- |
| errors | Error list | ReactNode\[] | - |
## Form.Provider
Provide linkage between forms. If a sub form with `name` prop update, it will auto trigger Provider related events. See [example](#components-form-demo-form-context).
2017-11-17 21:19:10 +08:00
| Property | Description | Type | Default |
| --- | --- | --- | --- |
2020-08-03 15:01:16 +08:00
| onFormChange | Triggered when a sub form field updates | function(formName: string, info: { changedFields, forms }) | - |
| onFormFinish | Triggered when a sub form submits | function(formName: string, info: { values, forms }) | - |
2017-11-17 21:19:10 +08:00
```jsx
<Form.Provider
onFormFinish={(name) => {
if (name === 'form1') {
// Do something...
}
}}
>
<Form name="form1">...</Form>
<Form name="form2">...</Form>
</Form.Provider>
```

| submit | Submit the form. It's same as click `submit` button | () => void | |
| validateFields | Validate fields. Use `recursive` to validate all the field in the path | (nameList?: [NamePath](#namepath)\[], { validateOnly?: boolean }) => Promise | `validateOnly`: 5.5.0, `recursive`: 5.9.0 |

validateFields()
.then((values) => {
/*
values:
{
username: 'username',

*/
});
```

## Hooks
### Form.useForm
`type Form.useForm = (): [FormInstance]`
Create Form instance to maintain data store.
### Form.useFormInstance
`type Form.useFormInstance = (): FormInstance`
Added in `4.20.0`. Get current context form instance to avoid pass as props between components:
```tsx
const Sub = () => {
const form = Form.useFormInstance();
return <Button onClick={() => form.setFieldsValue({})} />;
};
export default () => {
const [form] = Form.useForm();
return (
<Form form={form}>
<Sub />
</Form>
);
};
```
### Form.useWatch
`type Form.useWatch = (namePath: NamePath, formInstance?: FormInstance | WatchOptions): Value`
Watch the value of a field. You can use this to interact with other hooks like `useSWR` to reduce development costs:
```tsx
const Demo = () => {
const [form] = Form.useForm();
const userName = Form.useWatch('username', form);
const { data: options } = useSWR(`/api/user/${userName}`, fetcher);
return (
<Form form={form}>
<Form.Item name="username">
<AutoComplete options={options} />
</Form.Item>
</Form>
);
};
```
If your component is wrapped by `Form.Item`, you can omit the second argument, `Form.useWatch` will find the nearest `FormInstance` automatically.
By default `useWatch` only watches the registered field. If you want to watch the unregistered field, please use `preserve`:
```tsx
const Demo = () => {
const [form] = Form.useForm();
const age = Form.useWatch('age', { form, preserve: true });
console.log(age);
return (
<div>
<Button onClick={() => form.setFieldValue('age', 2)}>Update</Button>
<Form form={form}>
<Form.Item name="name">
<Input />
</Form.Item>
</Form>
</div>
);
};
```
### Form.Item.useStatus
`type Form.Item.useStatus = (): { status: ValidateStatus | undefined, errors: ReactNode[], warnings: ReactNode[] }`
Added in `4.22.0`. Could be used to get validate status of Form.Item. If this hook is not used under Form.Item, `status` would be `undefined`. Added `error` and `warnings` in `5.4.0`, Could be used to get error messages and warning messages of Form.Item:
```tsx
const CustomInput = ({ value, onChange }) => {
const { status, errors } = Form.Item.useStatus();
return (
<input
value={value}
onChange={onChange}
className={`custom-input-${status}`}
placeholder={(errors.length && errors[0]) || ''}
/>
);
};
export default () => (
<Form>
<Form.Item name="username">
<CustomInput />
</Form.Item>
</Form>
);
```
#### Difference between other data fetching method
Form only update the Field which changed to avoid full refresh perf issue. Thus you can not get real time value with `getFieldsValue` in render. And `useWatch` will rerender current component to sync with latest value. You can also use Field renderProps to get better performance if only want to do conditional render. If component no need care field value change, you can use `onValuesChange` to give to parent component to avoid current one rerender.
### Interface
2016-07-31 09:53:51 +08:00
#### NamePath
2016-07-31 09:53:51 +08:00
`string | number | (string | number)[]`
2023-07-27 09:56:05 +08:00
#### GetFieldsValue
`getFieldsValue` provides overloaded methods:
##### getFieldsValue(nameList?: true | [NamePath](#namepath)\[], filterFunc?: FilterFunc)
When `nameList` is empty, return all registered fields, including values of List (even if List has no Item children).
When `nameList` is `true`, return all values in store, including unregistered fields. For example, if you set the value of an unregistered Item through `setFieldsValue`, you can also get all values through `true`.
When `nameList` is an array, return the value of the specified path. Note that `nameList` is a nested array. For example, you need the value of a certain path as follows:
```tsx
// Single path
form.getFieldsValue([['user', 'age']]);
// multiple path
form.getFieldsValue([
['user', 'age'],
['preset', 'account'],

##### getFieldsValue({ strict?: boolean, filter?: FilterFunc })
New in `5.8.0`. Accept configuration parameters. When `strict` is `true`, only the value of Item will be matched. For example, in `{ list: [{ bamboo: 1, little: 2 }] }`, if List is only bound to the `bamboo` field, then `getFieldsValue({ strict: true })` will only get `{ list: [{ bamboo: 1 }] }`.
#### FilterFunc
2023-09-01 23:39:56 +08:00
To filter certain field values, `meta` will provide information related to the fields. For example, it can be used to retrieve values that have only been modified by the user, and so on.
2023-07-27 09:56:05 +08:00
```tsx
type FilterFunc = (meta: { touched: boolean; validating: boolean }) => boolean;
```

## FAQ
### Custom validator not working
It may be caused by your `validator` if it has some errors that prevents `callback` to be called. You can use `async` instead or use `try...catch` to catch the error:
```jsx
validator: async (rule, value) => {
throw new Error('Something wrong!');
}
// or
validator(rule, value, callback) => {
try {
throw new Error('Something wrong!');
} catch (err) {
callback(err);
}
}
```
### How does `name` fill value when it's an array?
2020-07-09 10:24:41 +08:00
`name` will fill value by array order. When there exists number in it and no related field in form store, it will auto convert field to array. If you want to keep it as object, use string like: `['1', 'name']`.
2020-02-23 01:26:35 +08:00
### Why is there a form warning when used in Modal?
> Warning: Instance created by `useForm` is not connect to any Form element. Forget to pass `form` prop?
2020-07-06 10:27:31 +08:00
Before Modal opens, children elements do not exist in the view. You can set `forceRender` on Modal to pre-render its children. Click [here](https://codesandbox.io/s/antd-reproduction-template-ibu5c) to view an example.
2020-07-06 10:27:31 +08:00
### Why is component `defaultValue` not working when inside Form.Item?
2020-07-06 10:27:31 +08:00
Components inside Form.Item with name property will turn into controlled mode, which makes `defaultValue` not work anymore. Please try `initialValues` of Form to set default value.
### Why can not call `ref` of Form at first time?
2020-08-25 11:27:01 +08:00
`ref` only receives the mounted instance. please ref React official doc: <https://reactjs.org/docs/refs-and-the-dom.html#accessing-refs>
2020-08-25 11:27:01 +08:00
### Why will `resetFields` re-mount component?
2020-07-06 10:27:31 +08:00
`resetFields` will re-mount component under Field to clean up customize component side effects (like async data, cached state, etc.). It's by design.
### Difference between Form initialValues and Item initialValue?
2020-07-06 10:27:31 +08:00
In most case, we always recommend to use Form `initialValues`. Use Item `initialValue` only with dynamic field usage. Priority follows the rules:
1. Form `initialValues` is the first priority
2020-07-06 10:27:31 +08:00
2. Field `initialValue` is secondary \*. Does not work when multiple Item with same `name` setting the `initialValue`
2023-07-06 17:51:38 +08:00
### Why can't `getFieldsValue` get value at first render?
`getFieldsValue` returns collected field data by default, but the Form.Item node is not ready at the first render. You can get all field data by `getFieldsValue(true)`.
### Why does `onFieldsChange` trigger three times on change when field sets `rules`?
Validating is also part of the value updating. It pass follow steps:
1. Trigger value change
2. Rule validating
3. Rule validated
In each `onFieldsChange`, you will get `false` > `true` > `false` with `isFieldValidating`.
### Why doesn't Form.List support `label` and need ErrorList to show errors?
Form.List use renderProps which mean internal structure is flexible. Thus `label` and `error` can not have best place. If you want to use antd `label`, you can wrap with Form.Item instead.
### Why can't Form.Item `dependencies` work on Form.List field?
2020-09-23 22:24:09 +08:00
Your name path should also contain Form.List `name`:
```tsx
<Form.List name="users">
{(fields) =>
fields.map((field) => (
2020-09-23 22:24:09 +08:00
<React.Fragment key={field.key}>
<Form.Item name={[field.name, 'name']} {...someRest1} />
<Form.Item name={[field.name, 'age']} {...someRest1} />
</React.Fragment>
))
}
</Form.List>
```
dependencies should be `['users', 0, 'name']`
### Why doesn't `normalize` support async?
React can not get correct interaction of controlled component with async value update. When user trigger `onChange`, component will do no response since `value` update is async. If you want to trigger value update async, you should use customize component to handle value state internal and pass sync value control to Form instead.

### `scrollToFirstError` and `scrollToField` not working?
1. use custom form control
See similar issues: [#28370](https://github.com/ant-design/ant-design/issues/28370) [#27994](https://github.com/ant-design/ant-design/issues/27994)
`scrollToFirstError` and `scrollToField` deps on `id` attribute passed to form control, please make sure that it hasn't been ignored in your custom form control. Check [codesandbox](https://codesandbox.io/s/antd-reproduction-template-forked-25nul?file=/index.js) for solution.
2021-04-12 17:48:28 +08:00
2. multiple forms on same page
If there are multiple forms on the page, and there are duplicate same `name` form item, the form scroll probably may find the form item with the same name in another form. You need to set a different `name` for the `Form` component to distinguish it.
2023-05-09 19:09:21 +08:00
### Continue, why not use `ref` to bind element?
Form can not get real DOM node when customize component not support `ref`. It will get warning in React Strict Mode if wrap with Class Component and call `findDOMNode`. So we use `id` to locate element.
2021-04-12 17:48:28 +08:00
### `setFieldsValue` do not trigger `onFieldsChange` or `onValuesChange`?
It's by design. Only user interactive can trigger the change event. This design is aim to avoid call `setFieldsValue` in change event which may makes loop calling.
### Why Form.Item not update value when children is nest?
Form.Item will inject `value` and `onChange` to children when render. Once your field component is wrapped, props will not pass to the correct node. Follow code will not work as expect:
```jsx
<Form.Item name="input">
<div>
<h3>I am a wrapped Input</h3>
<Input />
</div>
</Form.Item>
```
You can use HOC to solve this problem, don't forget passing props to form control component:
```jsx
const MyInput = (props) => (
<div>
<h3>I am a wrapped Input</h3>
<Input {...props} />
</div>
);
<Form.Item name="input">
<MyInput />
</Form.Item>;
```
