How to import

import { Checkbox, CheckboxGroup } from '@douyinfe/semi-ui';

Basic Usage

When the Checkbox is used individually, you can control whether to check it through the defaultChecked and checked attributes. When checked is passed in, it is controlled component.

import React from 'react';
import { Checkbox } from '@douyinfe/semi-ui';

() => (
  <Checkbox onChange={checked => console.log(checked)}>
    Semi Design
  </Checkbox>
)

import React from 'react';
import { Checkbox } from '@douyinfe/semi-ui';

() => (
  <Checkbox
    defaultChecked
    onChange={checked => console.log(checked)}
  >
    Semi Design
  </Checkbox>
)

You can use extra to add aextra information. The extra information usually is longer and even has line changes.

import React from 'react';
import { Checkbox } from '@douyinfe/semi-ui';

() => (
    <>
      <Checkbox
        extra='Semi Design is a design system developed and maintained by IES Front-end Team and UED Team'
      >
        Semi Design
      </Checkbox>
      <br/>
      <Checkbox
        extra='Semi Design is a design system developed and maintained by IES Front-end Team and UED Team'
        style={{ width: 400 }}
      >
        Semi Design
      </Checkbox>
    </>
)

Disabled

import React from 'react';
import { Checkbox } from '@douyinfe/semi-ui';

() => (
  <div>
    <Checkbox Default Checked={false} with>UnChecked Disabled</Checkbox>
    <br />
    <Checkbox defaultChecked disabled>Checked Disabled</Checkbox>
  </div>
)

Checkbox Group in JSX

By placing the Checkbox element inside the CheckboxGroup, you can declare the Checkbox group Using the Checkbox group, you can more conveniently control the selection of a group of Checkboxes through the defaultValue and value properties of the CheckboxGroup At this time, Checkbox does not need to declare defaultChecked and checked attributes

import React from 'react';
import { Checkbox, CheckboxGroup } from '@douyinfe/semi-ui';

() => (
  <CheckboxGroup style={{ width: '100%' }} defaultValue={['A', 'B']}>
    <Checkbox value="A">A</Checkbox>
    <Checkbox value="B">B</Checkbox>
    <Checkbox value="C">C</Checkbox>
    <Checkbox value="D">D</Checkbox>
    <Checkbox value="E">E</Checkbox>
  </CheckboxGroup>
)

Checkbox Group in options

You can pass an array using options to CheckboxGroup directly to generate a set of checkboxs.

import React from 'react';
import { CheckboxGroup } from '@douyinfe/semi-ui';

class App extends React.Component {

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

    const plainOptions = ['tiktok', 'vigo', 'helo'];
    const options = [
      { label: 'Aim for the highest', value: '1', extra: "Raise the bar. Wait for bigger gains. Find the best solutions by widening your perspective. Be attentive. Distill ideas down to their fundamental truths. Keep learning and growing" },
      { label: 'Be grounded & courageous', value: '2', extra:"Make your own discoveries. Dive deep into facts. Stay level-headed. Focus on impact. Assume ownership, take risks, break the mold. Rapid iterations, multiple possibilities." },
      { label: 'Be open & humble', value: '3', extra: "Trust yourself, trust each other. Be willing to offer and ask for help. Collaboration creates value. Approach problems with the big picture in mind. Be mindful and check your ego; stay open to different ideas." },
      { label: 'Be candid & clear', value: '4', extra: "Dare to share your honest opinions. It's okay to make mistakes. Own it when you do. Stick to the facts, identify issues, and avoid \'leader-pleasing.\' Be accurate and forthright; be methodical and focused."}
    ];
    const optionsWithDisabled = [
      { label: 'Photography', value: 'Photography' },
      { label: 'Movies', value: 'Movies' },
      { label: 'Running', value: 'Running', disabled: false },
    ];
    return (
      <div>
        <CheckboxGroup options={plainOptions} defaultValue={['tiktok']} onChange={onChange} />
        <br/><br/>
        <CheckboxGroup options={options} defaultValue={[]} onChange={onChange} />
        <br/><br/>
        <CheckboxGroup
          options={optionsWithDisabled}
          disabled
          defaultValue={['Photography']}
          onChange={onChange}
        />
      </div>
    )
  }
}

Layout Direction

By setting direction to horizontal or vertical, You can adjust the layout within the Checkbox Group.

import React from 'react';
import { CheckboxGroup } from '@douyinfe/semi-ui';

() => {
  const options = [
    { label: 'tiktok', value: 'tiktok' },
    { label: 'hotsoon', value: 'hotsoon' },
    { label: 'pipixia', value: 'pipixia' },
    { label: 'toutiao', value: 'toutiao' }
  ];
  return (
    <CheckboxGroup options={options} direction='horizontal' />
  )
}

Controlled Component

import React from 'react';
import { Checkbox, Button } from '@douyinfe/semi-ui';

class App extends React.Component {

  constructor() {
    super();
    this.state = {
      checked: true,
      disabled: false,
    }
    this.toggleChecked = this.toggleChecked.bind(this);
    this.toggleDisable = this.toggleDisable.bind(this);
    this.onChange = this.onChange.bind(this);
  }

  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 (
      <div>
        <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={{ marginLeft: '10px' }}
            type="primary"
            size="small"
            onClick={this.toggleDisable}
          >

() => {
    const plainOptions = ['Photography', 'Movies', 'Running'];
    const [checkedList, setCheckedList] = useState(['Photography', 'Running']);
    const [indeterminate, setIndeterminate] = useState(true);
    const [checkAll, setCheckall] = useState(false);
    const onChange = (checkedList) => {
      setCheckedList(checkedList);
      setIndeterminate(!!checkedList.length && checkedList.length < plainOptions.length);
      setCheckall(checkedList.length === plainOptions.length);
    }
    const onCheckAllChange = (e) => {
      console.log(e);
      setCheckedList(e.target.checked ? plainOptions : []);
      setIndeterminate(false);
      setCheckall(e.target.checked);
    }

    return (
        <div>
          <div style={{ paddingBottom: 8, borderBottom: '1px solid var(--semi-color-border)' }}>
            <Checkbox
              indeterminate={indeterminate}
              onChange={onCheckAllChange}
              checked={checkAll}
            >
