import { Input, AutoComplete } from 'antd';
import { UserOutlined } from '@ant-design/icons';

const renderTitle = (title: string) => {
  return (
    <span>
      {title}
      <a
        style={{ float: 'right' }}
        href="https://www.google.com/search?q=antd"
        target="_blank"
        rel="noopener noreferrer"
      >
        more
      </a>
    </span>
  );
};

const renderItem = (title: string, count: number) => {
  return {
    value: title,
    label: (
      <div
        style={{
          display: 'flex',
          justifyContent: 'space-between',
        }}
      >
        {title}
        <span>
          <UserOutlined /> {count}
        </span>
      </div>
    ),
  };
};

const options = [
  {
    label: renderTitle('Libraries'),
    options: [renderItem('AntDesign', 10000), renderItem('AntDesign UI', 10600)],
  },
  {
    label: renderTitle('Solutions'),
    options: [renderItem('AntDesign UI FAQ', 60100), renderItem('AntDesign FAQ', 30010)],
  },
  {
    label: renderTitle('Articles'),
    options: [renderItem('AntDesign design language', 100000)],

];

const Complete: React.FC = () => {
  return (
    <AutoComplete
      dropdownClassName="certain-category-search-dropdown"
      dropdownMatchSelectWidth={500}
      style={{ width: 250 }}
      options={options}
    >
      <Input.Search size="large" placeholder="input here" />
    </AutoComplete>
  );
};

ReactDOM.render(<Complete />, mountNode);
