react-checkbox-tree
A simple and elegant checkbox tree for React.
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.
