## en-US

Use `suffixIcon` to customize the selection box suffix icon, and use `expandIcon` to customize the current item expand icon.

```jsx
import { Cascader } from 'antd';
import { SmileOutlined } from '@ant-design/icons';

const options = [
  {
    value: 'zhejiang',
    label: 'Zhejiang',
    children: [
      {
        value: 'hangzhou',
        label: 'Hangzhou',
        children: [
          {
            value: 'xihu',
            label: 'West Lake',
          },
        ],
      },
    ],
  },
  {
    value: 'jiangsu',
    label: 'Jiangsu',
    children: [
      {
        value: 'nanjing',
        label: 'Nanjing',

        ],
      },
    ],
  },
];

function onChange(value) {
  console.log(value);
}

export default () => (
  <>
    <Cascader
      suffixIcon={<SmileOutlined />}
      options={options}
      onChange={onChange}
      placeholder="Please select"
    />
