React Checkbox

Demo: https://trendmicro-frontend.github.io/react-checkbox

Installation

1. Install the latest version of react and react-checkbox:

npm install --save react @trendmicro/react-checkbox

2. At this point you can import @trendmicro/react-checkbox and its styles in your application as follows:

import { Checkbox, CheckboxGroup } from '@trendmicro/react-checkbox';

// Be sure to include styles at some point, probably during your bootstraping
import '@trendmicro/react-checkbox/dist/react-checkbox.css';

Usage

<Checkbox label="Checkbox label" />

The label prop is optional, you can use children to pass through the component.

<Checkbox label="Checkbox label">
    <p style={{ marginLeft: 24 }}>
        Lorem ipsum dolor sit amet...
    </p>
</Checkbox>

<Checkbox>
    <span style={{ verticalAlign: 'middle', marginLeft: 8 }}>
        Lorem ipsum dolor sit amet...
    </span>
</Checkbox>

Uncontrolled Checkbox

// Default checked
<Checkbox defaultChecked />

// Default partially checked
<Checkbox defaultChecked defaultIndeterminate />

Controlled Checkbox

// Checked
<Checkbox checked />

// Partially checked
<Checkbox checked indeterminate />

CheckboxGroup

When rendering checkboxes deeply nested inside the checkbox group, you need to pass a depth prop to limit the recursion depth.

<CheckboxGroup
    name="comic"
    value={this.state.value}
    depth={3} // This is needed to minimize the recursion overhead
    onChange={(value, event) => {
        this.setState({ value: value });
    }}
>
    <div className="row">
        <div className="col-xs-12 col-sm-6">
            <Checkbox label="Batman (DC)" value="dc:batman" />
            <Checkbox label="Hulk (Marvel)" value="marvel:hulk" />
        </div>
        <div className="col-xs-12 col-sm-6">
            <Checkbox label="Superman (DC)" value="dc:superman" />
            <Checkbox label="Spider-Man (Marvel)" value="marvel:spiderman" disabled />
        </div>
    </div>
</CheckboxGroup>

Prevent onChange Propagation

You may need to use event.stopPropagation() to stop onChange propagation when wrapping an input element inside the CheckboxGroup or Checkbox component.

<CheckboxGroup
    name="checkboxgroup"
    value={this.state.value}
    onChange={(value, event) => {
        this.setState({ value: value });
    }}
>
    <Checkbox label="First option" value="one">
        <div style={{ marginLeft: 22 }}>
            <input
                type="text"
                onChange={(event) => {
                    // Prevent onChange propagation
                    event.stopPropagation();
                }}
            />
        </div>
    </Checkbox>
    <Checkbox label="Second option" value="two">
        <div style={{ marginLeft: 22 }}>
            <input
                type="text"
                onChange={(event) => {
                    // Prevent onChange propagation
                    event.stopPropagation();
                }}
            />
        </div>
    </Checkbox>
</CheckboxGroup>
