import { Search, User } from '@ant-design/icons';

const { Option, OptGroup } = AutoComplete;

function 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>
  );
}

function renderItem(title: string, count: number) {
  return {
    value: title,
    label: (
      <>
        {title}
        <span className="certain-search-item-count">
          <User /> {count}
        </span>
      </>
    ),
  };
}

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)],
  },
];

function Complete() {
  return (
    <div className="certain-category-search-wrapper" style={{ width: 250 }}>
      <AutoComplete
        className="certain-category-search"
        dropdownClassName="certain-category-search-dropdown"
        dropdownMatchSelectWidth={500}
        style={{ width: '100%' }}
