const { Option } = Select;
const layout = {

wrapperCol: { span: 16 },
};
const tailLayout = {
wrapperCol: { offset: 8, span: 16 },
};
const Demo = () => {
const [form] = Form.useForm();
const onGenderChange = (value: string) => {
switch (value) {
case 'male':
form.setFieldsValue({ note: 'Hi, man!' });
return;
case 'female':
form.setFieldsValue({ note: 'Hi, lady!' });
return;
case 'other':
form.setFieldsValue({ note: 'Hi there!' });
}
};
const onFinish = (values: any) => {
console.log(values);
};
const onReset = () => {
form.resetFields();
};
const onFill = () => {
form.setFieldsValue({
note: 'Hello world!',
gender: 'male',
});
};
return (
<Form {...layout} form={form} name="control-hooks" onFinish={onFinish}>
