How can I add paging on the Select of Antd ? Because getting data from the interface is huge. So I want to implement paging. But the document api don't support it.

import { Select} from 'antd';
const Option = Select.Option;

let provinceData = []; 


render:

 <Select>
      {provinceData.map(province => <Option>{province}</Option>)}
 </Select>

provinceData that getting from the interface can be huge，so I expect to implement paging on antd select. When I slide to the Select bottom, it reload the new data.

If you have huge data, avoid showing in dropdown. But still you like to implement what you want, here is the crude form of dropdown with pagination.

Implementation: CodeSandBox Link

import React from "react";
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import "./index.css";
import { Select, Icon, Divider, Pagination, Button } from "antd";
import faker from "faker";

const Option = Select.Option;
let names = [];
const count = 100;
const pageSize = 5;
for (let i = 0; i < count; i++) {
  names.push(faker.name.firstName());
}

const getNames = pageNumber => {
  let toSendNames = [];
  for (let i = (pageNumber - 1) * pageSize; i < pageNumber * pageSize; i++) {
    toSendNames.push(names[i]);
  }
  console.log(toSendNames);
  return toSendNames;
};

class Test extends React.Component {
  state = {
    isOpen: false,
    currentPage: 1
  };

  paginationRef = React.createRef();

  render = () => {
    return (
      <div>
        <Select
          style={{ width: 250 }}
          onFocus={() => {
            this.setState({ isOpen: true });
          }}
          open={this.state.isOpen}
          dropdownRender={menu => (
            <div>
              {menu}
              <Divider style={{ margin: "4px 0" }} />
              <div style={{ padding: "8px", textAlign: "center" }}>
                <Pagination
                  simple
                  current={this.state.currentPage}
                  total={count}
                  onChange={pageIndex => {
                    this.setState({
                      currentPage: pageIndex
                    });
                  }}
                />
                <br />
                <Button
                  type="ghost"
                  style={{ width: "100%", borderColor: "red" }}
                  size="small"
                  onClick={() =>
                    this.setState({
                      isOpen: false
                    })
                  }
                >
                  Close
                </Button>
              </div>
            </div>
          )}
        >
          {getNames(this.state.currentPage).map(item => {
            return <Option value={item}>{item}</Option>;
          })}
        </Select>
      </div>
    );
  };
}

ReactDOM.render(<Test />, document.getElementById("container"));

i hope this would help.
