import React, { Component } from 'react';
import IceContainer from '@icedesign/container';
import { Input, Button, Select, Checkbox, Form, NumberPicker, SplitButton } from '@alifd/next';

const CheckboxGroup = Checkbox.Group;
const FormItem = Form.Item;

const formItemLayout = {
  labelCol: { xxs: 8, s: 3, l: 3 },
  wrapperCol: { s: 12, l: 10 }
};

export default class GroupedForm extends Component {
  static displayName = 'GroupedForm';

  reset = () => {
  }

  formChange = (values, field) => {
    console.log(values, field)
  }
