reactjs-checkbox-tree (Fork by royaltics-solutions)

A simple and elegant checkbox tree for React.

About this fork

This project is a refactor of the original reactjs-checkbox-tree by Jake Zatecky and contributors, updated and recompiled to be fully compatible with Vite 5 (2025) and its latest dependencies, with React 19 support.

Major changes include:

• Full refactor to support Vite build system and ecosystem.
• Updated peerDependencies and devDependencies to React 18/19 and Vite 5.
• Removal of LESS/SCSS in favor of pure CSS with CSS variables (--vars) for styling.
• Updated typings for better TypeScript support.
• Complete rewrite of icons handling with ReactNode type and partial overrides.
• Codebase split and optimized for modern React and TypeScript usage.

Full credit to original author Jake Zatecky and all contributors at reactjs-checkbox-tree homepage.

This fork is maintained by royaltics-solutions due to lack of continuity in the original project.

Installation

yarn add reactjs-checkbox-tree
or
npm install reactjs-checkbox-tree --save

Usage

Import the pure CSS style:

import 'reactjs-checkbox-tree/lib/reactjs-checkbox-tree.css';
//Basic example:

import React, { useState } from 'react';
import CheckboxTree from 'reactjs-checkbox-tree';

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

function Widget() {
  const [checked, setChecked] = useState([]);
  const [expanded, setExpanded] = useState([]);

  return (
    <CheckboxTree
      nodes={nodes}
      checked={checked}
      expanded={expanded}
      onCheck={setChecked}
      onExpand={setExpanded}
    />
  );
}

Icons customization

Use iconsClass="fa4" for FontAwesome 4 support, or override icons with the icons prop:

<CheckboxTree
  ...
  iconsClass="fa4"
  icons={{
    check: <span className="rct-icon rct-icon-check" />,
    uncheck: <span className="rct-icon rct-icon-uncheck" />,
    halfCheck: <span className="rct-icon rct-icon-half-check" />,
    expandClose: <span className="rct-icon rct-icon-expand-close" />,
    expandOpen: <span className="rct-icon rct-icon-expand-open" />,
    expandAll: <span className="rct-icon rct-icon-expand-all" />,
    collapseAll: <span className="rct-icon rct-icon-collapse-all" />,
    parentClose: <span className="rct-icon rct-icon-parent-close" />,
    parentOpen: <span className="rct-icon rct-icon-parent-open" />,
    leaf: <span className="rct-icon rct-icon-leaf" />,
  }}
/>

Or integrate with @fortawesome/reactjs-fontawesome:

import { FontAwesomeIcon } from '@fortawesome/reactjs-fontawesome'

<CheckboxTree
  ...
  icons={{
    check: <FontAwesomeIcon className="rct-icon rct-icon-check" icon="check-square" />,
    uncheck: <FontAwesomeIcon className="rct-icon rct-icon-uncheck" icon={['fas', 'square']} />,
    halfCheck: <FontAwesomeIcon className="rct-icon rct-icon-half-check" icon="check-square" />,
    expandClose: <FontAwesomeIcon className="rct-icon rct-icon-expand-close" icon="chevron-right" />,
    expandOpen: <FontAwesomeIcon className="rct-icon rct-icon-expand-open" icon="chevron-down" />,
    expandAll: <FontAwesomeIcon className="rct-icon rct-icon-expand-all" icon="plus-square" />,
    collapseAll: <FontAwesomeIcon className="rct-icon rct-icon-collapse-all" icon="minus-square" />,
    parentClose: <FontAwesomeIcon className="rct-icon rct-icon-parent-close" icon="folder" />,
    parentOpen: <FontAwesomeIcon className="rct-icon rct-icon-parent-open" icon="folder-open" />,
    leaf: <FontAwesomeIcon className="rct-icon rct-icon-leaf-close" icon="file" />
  }}
/>
