A simple and elegant checkbox tree for React.

Demo

Usage

Installation

Install the library using your favorite dependency manager:

yarn add react-checkbox-tree

Using npm:

npm install react-checkbox-tree --save

Note – This library makes use of Font Awesome styles and expects them to be loaded in the browser.

Include CSS

For your convenience, the library's styles can be consumed utilizing one of the following files:

  • node_modules/react-checkbox-tree/lib/react-checkbox-tree.css
  • node_modules/react-checkbox-tree/src/less/react-checkbox-tree.less
  • node_modules/react-checkbox-tree/src/scss/react-checkbox-tree.scss

Either include one of these files in your stylesheets or utilize a CSS loader:

import 'react-checkbox-tree/lib/react-checkbox-tree.css';

Render Component

A quick usage example is included below. Note that the react-checkbox-tree component is controlled. In other words, it is stateless. You must update its checked and expanded properties whenever a change occurs.

import React from 'react';
import CheckboxTree from 'react-checkbox-tree';

const nodes = [{
    value: 'mars',
    label: 'Mars',
    children: [
        { value: 'phobos', label: 'Phobos' },
        { value: 'deimos', label: 'Deimos' },
    ],
}];

class Widget extends React.Component {
    constructor() {
        super();

        this.state = {
            checked: [],
            expanded: [],
        };
    }

    render() {
        return (
            <CheckboxTree
                nodes={nodes}
                checked={this.state.checked}
                expanded={this.state.expanded}
                onCheck={checked => this.setState({ checked })}
                onExpand={expanded => this.setState({ expanded })}
            />
        );
    }
}

All node objects must have a unique value. This value is serialized into the checked and expanded arrays and is also used for performance optimizations.
