React Tree View Component. Data-Driven, Fast, Efficient and Customisable.

npm install react-treebeard --save 

An online example from the /example directory can be found here: Here

'use strict'; import React from 'react'; import ReactDOM from 'react-dom'; import {Treebeard} from 'react-treebeard'; const data = { name: 'root', toggled: true, children: [ { name: 'parent', children: [ { name: 'child1' }, { name: 'child2' } ] }, { name: 'loading parent', loading: true, children: [] }, { name: 'parent', children: [ { name: 'nested parent', children: [ { name: 'nested child 1' }, { name: 'nested child 2' } ] } ] } ] }; class TreeExample extends React.Component { constructor(props){ super(props); this.state = {}; this.onToggle = this.onToggle.bind(this); } onToggle(node, toggled){ if(this.state.cursor){this.state.cursor.active = false;} node.active = true; if(node.children){ node.toggled = toggled; } this.setState({ cursor: node }); } render(){ return ( <Treebeard data={data} onToggle={this.onToggle} /> ); } } const content = document.getElementById('content'); ReactDOM.render(<TreeExample/>, content);

PropTypes.oneOfType([PropTypes.object,PropTypes.array]).isRequired

Data that drives the tree view. State-driven effects can be built by manipulating the attributes in this object. Also supports an array for multiple nodes at the root level. An example can be found in example/data.js

PropTypes.func

Callback function when a node is toggled / clicked. Passes 2 attributes: the data node and it's toggled boolean state.

PropTypes.object

Sets the treeview styling. Defaults to src/themes/default.

PropTypes.oneOfType([PropTypes.object, PropTypes.bool])

Sets the treeview animations. Set to false if you want to turn off animations. See velocity-react for more details. Defaults to src/themes/animations.

PropTypes.bool Enable / disable checkbox element for each node. Defaults to false.

PropTypes.string To set the checkbox field value which need to be used. Defaults to name.

PropTypes.func

Callback function when a checbox is checked / unchecked. Passes 2 attributes: the data node and it's checked boolean value.

handleCheckbox(node, isChecked) { node.checked = isChecked; this.setState({cursor: node}); } 

PropTypes.object

Decorates the treeview. Here you can use your own Container, Header, Toggle and Loading components. Defaults to src/decorators. See example below:

const decorators = { Loading: (props) => { return ( <div style={props.style}> loading... </div> ); }, Toggle: (props) => { return ( <div style={props.style}> <svg height={props.height} width={props.width}> // Vector Toggle Here </svg> </div> ); }, Header: (props) => { return ( <div style={props.style}> {props.node.name} </div> ); }, Container: (props) => { return ( <div onClick={this.props.onClick}> // Hide Toggle When Terminal Here <this.props.decorators.Toggle/> <this.props.decorators.Header/> </div> ); } }; <Treebeard data={...} decorators={decorators}/>

{ id: '[optional] string', name: 'string', children: '[optional] array', toggled: '[optional] boolean', active: '[optional] boolean', loading: '[optional] boolean', decorators: '[optional] object', animations: '[optional] object' checked: '[optional] boolean' },

The component key. If not defined, an auto-generated index is used.

The name prop passed into the Header component.

The children attached to the node. This value populates the subtree at the specific node. Each child is built from the same basic data structure. Tip: Make this an empty array, if you want to asynchronously load a potential parent.

Toggled flag. Sets the visibility of a node's children. It also sets the state for the toggle decorator.

Active flag. If active, the node will be highlighted. The highlight is derived from the node.activeLink style object in the theme.

Loading flag. It will populate the treeview with the loading component. Useful when asynchronously pulling the data into the treeview.

Attach specific decorators / animations to a node. Provides the low level functionality to create visuals on a node-by-node basis. These structures are the same as the top level props, described above.

Checked flag. Validate node checkbox should display as checked or not .
