Select

Select component to select value from options.

When To Use#

A dropdown menu for displaying choices - an elegant alternative to the native <select> element.
Utilizing Radio is recommended when there are fewer total options (less than 5).

Examples

Basic Usage.

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

function handleChange(value) {
  console.log(`selected ${value}`);
}

ReactDOM.render(
  <div>
    <Select defaultValue="lucy" style={{ width: 120 }} onChange={handleChange}>
      <Option value="jack">Jack</Option>
      <Option value="lucy">Lucy</Option>
      <Option value="disabled" disabled>Disabled</Option>
      <Option value="Yiminghe">yiminghe</Option>
    </Select>
    <Select defaultValue="lucy" style={{ width: 120 }} allowClear disabled>
      <Option value="lucy">Lucy</Option>
    </Select>
  </div>
, mountNode);

Select with search field

Search the options while expanded.

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

function handleChange(value) {
  console.log(`selected ${value}`);
}

function handleBlur() {
  console.log('blur');
}

function handleFocus() {
  console.log('focus');
}

ReactDOM.render(
  <Select
    showSearch
    style={{ width: 200 }}
    placeholder="Select a person"
    optionFilterProp="children"
    onChange={handleChange}
    onFocus={handleFocus}
    onBlur={handleBlur}
    filterOption={(input, option) => option.props.children.toLowerCase().indexOf(input.toLowerCase()) >= 0}
  >
    <Option value="jack">Jack</Option>
    <Option value="lucy">Lucy</Option>
    <Option value="tom">Tom</Option>
  </Select>
, mountNode);

Tags

Select with tags, transform input to tag (scroll the menu)

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

const children = [];
for (let i = 10; i < 36; i++) {
  children.push(<Option key={i.toString(36) + i}>{i.toString(36) + i}</Option>);
}

function handleChange(value) {
  console.log(`selected ${value}`);
}

ReactDOM.render(
  <Select
    mode="tags"
    style={{ width: '100%' }}
    placeholder="Tags Mode"
    onChange={handleChange}
  >
    {children}
  </Select>
, mountNode);

Option Group

Using OptGroup to group the options.

import { Select } from 'antd';
const { Option, OptGroup } = Select;

function handleChange(value) {
  console.log(`selected ${value}`);
}

ReactDOM.render(
  <Select
    defaultValue="lucy"
    style={{ width: 200 }}
    onChange={handleChange}
  >
    <OptGroup label="Manager">
      <Option value="jack">Jack</Option>
      <Option value="lucy">Lucy</Option>
    </OptGroup>
    <OptGroup label="Engineer">
      <Option value="Yiminghe">yiminghe</Option>
    </OptGroup>
  </Select>
, mountNode);

Search Box

Autocomplete with remote ajax data.

import { Select } from 'antd';
import jsonp from 'fetch-jsonp';
import querystring from 'querystring';
const Option = Select.Option;

let timeout;
let currentValue;

function fetch(value, callback) {
  if (timeout) {
    clearTimeout(timeout);
    timeout = null;
  }
  currentValue = value;

  function fake() {
    const str = querystring.encode({
      code: 'utf-8',
      q: value,
    });
    jsonp(`https://suggest.taobao.com/sug?${str}`)
      .then(response => response.json())
      .then((d) => {
        if (currentValue === value) {
          const result = d.result;
          const data = [];
          result.forEach((r) => {
            data.push({
              value: r[0],
              text: r[0],
            });
          });
          callback(data);
        }
      });
  }

  timeout = setTimeout(fake, 300);
}

class SearchInput extends React.Component {
  state = {
    data: [],
    value: '',
  }
  handleChange = (value) => {
    this.setState({ value });
    fetch(value, data => this.setState({ data }));
  }
  render() {
    const options = this.state.data.map(d => <Option key={d.value}>{d.text}</Option>);
    return (
      <Select
        mode="combobox"
        value={this.state.value}
        placeholder={this.props.placeholder}
        style={this.props.style}
        defaultActiveFirstOption={false}
        showArrow={false}
        filterOption={false}
        onChange={this.handleChange}
      >
        {options}
      </Select>
    );
  }
}

ReactDOM.render(
  <SearchInput placeholder="input search text" style={{ width: 200 }} />
, mountNode);

Automatic tokenization

Try to copy Lucy,Jack to the input. Only available in tags and multiple mode.

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

const children = [];
for (let i = 10; i < 36; i++) {
  children.push(<Option key={i.toString(36) + i}>{i.toString(36) + i}</Option>);
}

function handleChange(value) {
  console.log(`selected ${value}`);
}

ReactDOM.render(
  <Select
    mode="tags"
    style={{ width: '100%' }}
    onChange={handleChange}
    tokenSeparators={[',']}
  >
    {children}
  </Select>
, mountNode);

LargeDefaultSmall

Sizes

The height of the input field for the select defaults to 32px. If size is set to large, the height will be 40px, and if set to small, 24px.

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

const children = [];
for (let i = 10; i < 36; i++) {
  children.push(<Option key={i.toString(36) + i}>{i.toString(36) + i}</Option>);
}

function handleChange(value) {
  console.log(`Selected: ${value}`);
}

class SelectSizesDemo extends React.Component {
  state = {
    size: 'default',
  };

  handleSizeChange = (e) => {
    this.setState({ size: e.target.value });
  }

  render() {
    const { size } = this.state;
    return (
      <div>
        <Radio.Group value={size} onChange={this.handleSizeChange}>
          <Radio.Button value="large">Large</Radio.Button>
          <Radio.Button value="default">Default</Radio.Button>
          <Radio.Button value="small">Small</Radio.Button>
        </Radio.Group>
        <br /><br />
        <Select
          size={size}
          defaultValue="a1"
          onChange={handleChange}
          style={{ width: 200 }}
        >
          {children}
        </Select>
        <br />
        <Select
          mode="combobox"
          size={size}
          defaultValue="a1"
          onChange={handleChange}
          style={{ width: 200 }}
        >
          {children}
        </Select>
        <br />
        <Select
          mode="multiple"
          size={size}
          placeholder="Please select"
          defaultValue={['a10', 'c12']}
          onChange={handleChange}
          style={{ width: '100%' }}
        >
          {children}
        </Select>
        <br />
        <Select
          mode="tags"
          size={size}
          placeholder="Please select"
          defaultValue={['a10', 'c12']}
          onChange={handleChange}
          style={{ width: '100%' }}
        >
          {children}
        </Select>
      </div>
    );
  }
}

ReactDOM.render(<SelectSizesDemo />, mountNode);
.code-box-demo .ant-select {
  margin: 0 8px 10px 0;
}

#components-select-demo-search-box .code-box-demo .ant-select {
  margin: 0;
}

multiple selection

Multiple selection, selecting from existing items (scroll the menu).

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

const children = [];
for (let i = 10; i < 36; i++) {
  children.push(<Option key={i.toString(36) + i}>{i.toString(36) + i}</Option>);
}

function handleChange(value) {
  console.log(`selected ${value}`);
}

ReactDOM.render(
  <Select
    mode="multiple"
    style={{ width: '100%' }}
    placeholder="Please select"
    defaultValue={['a10', 'c12']}
    onChange={handleChange}
  >
    {children}
  </Select>
, mountNode);

Automatic completion

Automatic completion of select input.

Using the AutoComplete component is strongly recommended instead as it is more flexible and capable.

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

class App extends React.Component {
  state = {
    options: [],
  }
  handleChange = (value) => {
    let options;
    if (!value || value.indexOf('@') >= 0) {
      options = [];
    } else {
      options = ['gmail.com', '163.com', 'qq.com'].map((domain) => {
        const email = `${value}@${domain}`;
        return <Option key={email}>{email}</Option>;
      });
    }
    this.setState({ options });
  }
  render() {
    // filterOption needs to be false，as the value is dynamically generated
    return (
      <Select
        mode="combobox"
        style={{ width: 200 }}
        onChange={this.handleChange}
        filterOption={false}
        placeholder="Enter the account name"
      >
        {this.state.options}
      </Select>
    );
  }
}

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

coordinate

Coordinating the selection of provinces and cities is a common use case and demonstrates how selection can be coordinated.

Using the Cascader component is strongly recommended instead as it is more flexible and capable.

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

const provinceData = ['Zhejiang', 'Jiangsu'];
const cityData = {
  Zhejiang: ['Hangzhou', 'Ningbo', 'Wenzhou'],
  Jiangsu: ['Nanjing', 'Suzhou', 'Zhenjiang'],
};

class App extends React.Component {
  state = {
    cities: cityData[provinceData[0]],
    secondCity: cityData[provinceData[0]][0],
  }
  handleProvinceChange = (value) => {
    this.setState({
      cities: cityData[value],
      secondCity: cityData[value][0],
    });
  }
  onSecondCityChange = (value) => {
    this.setState({
      secondCity: value,
    });
  }
  render() {
    const provinceOptions = provinceData.map(province => <Option key={province}>{province}</Option>);
    const cityOptions = this.state.cities.map(city => <Option key={city}>{city}</Option>);
    return (
      <div>
        <Select defaultValue={provinceData[0]} style={{ width: 90 }} onChange={this.handleProvinceChange}>
          {provinceOptions}
        </Select>
        <Select value={this.state.secondCity} style={{ width: 90 }} onChange={this.onSecondCityChange}>
          {cityOptions}
        </Select>
      </div>
    );
  }
}

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

Get value of selected item

As a default behavior, the onChange callback can only get the value of the selected item. The labelInValue prop can be used to get the label property of the selected item.

The label of the selected item will be packed as an object for passing to the onChange callback.

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

function handleChange(value) {
  console.log(value); // { key: "lucy", label: "Lucy (101)" }
}

ReactDOM.render(
  <Select labelInValue defaultValue={{ key: 'lucy' }} style={{ width: 120 }} onChange={handleChange}>
    <Option value="jack">Jack (100)</Option>
    <Option value="lucy">Lucy (101)</Option>
  </Select>
, mountNode);

Search and Select Users

A complete multiple select sample with remote search, debounce fetch, ajax callback order flow, and loading state.

import { Select, Spin } from 'antd';
import debounce from 'lodash/debounce';
const Option = Select.Option;

class UserRemoteSelect extends React.Component {
  constructor(props) {
    super(props);
    this.lastFetchId = 0;
    this.fetchUser = debounce(this.fetchUser, 800);
  }
  state = {
    data: [],
    value: [],
    fetching: false,
  }
  fetchUser = (value) => {
    console.log('fetching user', value);
    this.lastFetchId += 1;
    const fetchId = this.lastFetchId;
    this.setState({ data: [], fetching: true });
    fetch('https://randomuser.me/api/?results=5')
      .then(response => response.json())
      .then((body) => {
        if (fetchId !== this.lastFetchId) { // for fetch callback order
          return;
        }
        const data = body.results.map(user => ({
          text: `${user.name.first} ${user.name.last}`,
          value: user.login.username,
        }));
        this.setState({ data, fetching: false });
      });
  }
  handleChange = (value) => {
    this.setState({
      value,
      data: [],
      fetching: false,
    });
  }
  render() {
    const { fetching, data, value } = this.state;
    return (
      <Select
        mode="multiple"
        labelInValue
        value={value}
        placeholder="Select users"
        notFoundContent={fetching ? <Spin size="small" /> : null}
        filterOption={false}
        onSearch={this.fetchUser}
        onChange={this.handleChange}
        style={{ width: '100%' }}
      >
        {data.map(d => <Option key={d.value}>{d.text}</Option>)}
      </Select>
    );
  }
}

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