import React from 'react';
import Cascader from '../src';

const addressOptions = [
  {
    label: '浙江',
    value: 'zj',
    children: [
      {
        label: '杭州',
        value: 'hangzhou',
        children: [
          {
            label: '富阳',
            value: 'fuyang',
          },
          {
            label: '余杭',
            value: 'yuhang',
          },
        ],
      },
    ],
  },
];

const Demo = () => {
  return (
    <>
      <Cascader style={{ width: 200 }} options={addressOptions} checkable={true} allowClear />
    </>
  );
};

export default Demo;
