Checkbox

Checkbox component.

When To Use#

Used for selecting multiple values from several options.
If you use only one checkbox, it is the same as using Switch to toggle between two states. The difference is that Switch will trigger the state change directly, but Checkbox just marks the state as changed and this needs to be submitted.

Examples

Checkbox

Basic

Basic usage of checkbox.

import { Checkbox } from 'antd';

function onChange(e) {
  console.log(`checked = ${e.target.checked}`);
}

ReactDOM.render(<Checkbox onChange={onChange}>Checkbox</Checkbox>, mountNode);

Checked-Enabled

Controlled Checkbox

Communicated with other components.

import { Checkbox, Button } from 'antd';

class App extends React.Component {
  state = {
    checked: true,
    disabled: false,
  };

  toggleChecked = () => {
    this.setState({ checked: !this.state.checked });
  };

  toggleDisable = () => {
    this.setState({ disabled: !this.state.disabled });
  };

  onChange = e => {
    console.log('checked = ', e.target.checked);
    this.setState({
      checked: e.target.checked,
    });
  };

  render() {
    const label = `${this.state.checked ? 'Checked' : 'Unchecked'}-${
      this.state.disabled ? 'Disabled' : 'Enabled'
    }`;
    return (
      <>
        <p style={{ marginBottom: '20px' }}>
          <Checkbox
            checked={this.state.checked}
            disabled={this.state.disabled}
            onChange={this.onChange}
          >
            {label}
          </Checkbox>
        </p>
        <p>
          <Button type="primary" size="small" onClick={this.toggleChecked}>
            {!this.state.checked ? 'Check' : 'Uncheck'}
          </Button>
          <Button
            style={{ margin: '0 10px' }}
            type="primary"
            size="small"
            onClick={this.toggleDisable}
          >
            {!this.state.disabled ? 'Disable' : 'Enable'}
          </Button>
        </p>
      </>
    );
  }
}

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

Check all

ApplePearOrange

Check all

The indeterminate property can help you to achieve a 'check all' effect.

import { Checkbox } from 'antd';

const CheckboxGroup = Checkbox.Group;

const plainOptions = ['Apple', 'Pear', 'Orange'];
const defaultCheckedList = ['Apple', 'Orange'];

class App extends React.Component {
  state = {
    checkedList: defaultCheckedList,
    indeterminate: true,
    checkAll: false,
  };

  onChange = checkedList => {
    this.setState({
      checkedList,
      indeterminate: !!checkedList.length && checkedList.length < plainOptions.length,
      checkAll: checkedList.length === plainOptions.length,
    });
  };

  onCheckAllChange = e => {
    this.setState({
      checkedList: e.target.checked ? plainOptions : [],
      indeterminate: false,
      checkAll: e.target.checked,
    });
  };

  render() {
    return (
      <>
        <div className="site-checkbox-all-wrapper">
          <Checkbox
            indeterminate={this.state.indeterminate}
            onChange={this.onCheckAllChange}
            checked={this.state.checkAll}
          >
            Check all
          </Checkbox>
        </div>
        <br />
        <CheckboxGroup
          options={plainOptions}
          value={this.state.checkedList}
          onChange={this.onChange}
        />
      </>
    );
  }
}

ReactDOM.render(<App />, mountNode);
.site-checkbox-all-wrapper {
  border-bottom: 1px solid #e9e9e9;
}

Disabled

Disabled checkbox.

import { Checkbox } from 'antd';

ReactDOM.render(
  <>
    <Checkbox defaultChecked={false} disabled />
    <br />
    <Checkbox defaultChecked disabled />
  </>,
  mountNode,
);

Checkbox Group

Generate a group of checkboxes from an array.

import { Checkbox } from 'antd';

function onChange(checkedValues) {
  console.log('checked = ', checkedValues);
}

const plainOptions = ['Apple', 'Pear', 'Orange'];
const options = [
  { label: 'Apple', value: 'Apple' },
  { label: 'Pear', value: 'Pear' },
  { label: 'Orange', value: 'Orange' },
];
const optionsWithDisabled = [
  { label: 'Apple', value: 'Apple' },
  { label: 'Pear', value: 'Pear' },
  { label: 'Orange', value: 'Orange', disabled: false },
];

ReactDOM.render(
  <>
    <Checkbox.Group options={plainOptions} defaultValue={['Apple']} onChange={onChange} />
    <br />
    <br />
    <Checkbox.Group options={options} defaultValue={['Pear']} onChange={onChange} />
    <br />
    <br />
    <Checkbox.Group
      options={optionsWithDisabled}
      disabled
      defaultValue={['Apple']}
      onChange={onChange}
    />
  </>,
  mountNode,
);

Use with Grid

We can use Checkbox and Grid in Checkbox.Group, to implement complex layout.

import { Checkbox, Row, Col } from 'antd';

function onChange(checkedValues) {
  console.log('checked = ', checkedValues);
}

ReactDOM.render(
  <Checkbox.Group style={{ width: '100%' }} onChange={onChange}>
    <Row>
      <Col span={8}>
        <Checkbox value="A">A</Checkbox>
      </Col>
      <Col span={8}>
        <Checkbox value="B">B</Checkbox>
      </Col>
      <Col span={8}>
        <Checkbox value="C">C</Checkbox>
      </Col>
      <Col span={8}>
        <Checkbox value="D">D</Checkbox>
      </Col>
      <Col span={8}>
        <Checkbox value="E">E</Checkbox>
      </Col>
    </Row>
  </Checkbox.Group>,
  mountNode,
);
