# react-treebeard [![Build Status](https://travis-ci.org/storybookjs/react-treebeard.svg?branch=master)](https://travis-ci.org/storybookjs/react-treebeard) [![Coverage Status](https://coveralls.io/repos/storybookjs/react-treebeard/badge.svg?branch=master&service=github)](https://coveralls.io/github/storybookjs/react-treebeard?branch=master) React Tree View Component. Data-Driven, Fast, Efficient and Customisable. ### Install ``` npm install react-treebeard --save ``` ### [Example](http://storybookjs.github.io/react-treebeard/) An online example from the `/example` directory can be found here: [Here](http://storybookjs.github.io/react-treebeard/) ### Quick Start ```javascript import React, {PureComponent} 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 PureComponent { constructor(props){ super(props); this.state = {data}; } onToggle(node, toggled){ const {cursor, data} = this.state; if (cursor) { this.setState(() => ({cursor, active: false})); } node.active = true; if (node.children) { node.toggled = toggled; } this.setState(() => ({cursor: node, data: Object.assign({}, data)})); } render(){ const {data} = this.state; return ( ); } } const content = document.getElementById('content'); ReactDOM.render(, content); ``` If you use react-hooks you should do something like this: ```javascript import React, {useState} from 'react'; const TreeExample = () => { const [data, setData] = useState(data); const [cursor, setCursor] = useState(false); const onToggle = (node, toggled) => { if (cursor) { cursor.active = false; } node.active = true; if (node.children) { node.toggled = toggled; } setCursor(node); setData(Object.assign({}, data)) } return ( ) } const content = document.getElementById('content'); ReactDOM.render(, content); ``` ### Prop Values #### data `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` #### onToggle `PropTypes.func` Callback function when a node is toggled / clicked. Passes 2 attributes: the data node and it's toggled boolean state. #### style `PropTypes.object` Sets the treeview styling. Defaults to `src/themes/default`. #### animations `PropTypes.oneOfType([PropTypes.object, PropTypes.bool])` Sets the treeview animations. Set to `false` if you want to turn off animations. See [velocity-react](https://github.com/twitter-fabric/velocity-react) for more details. Defaults to `src/themes/animations`. #### decorators `PropTypes.object` Decorates the treeview. Here you can use your own Container, Header, Toggle and Loading components. Defaults to `src/decorators`. See example below: ```javascript const decorators = { Loading: (props) => { return (

); }, Toggle: (props) => { return (

); }, Header: (props) => { return (

{props.node.name}

); }, Container: (props) => { return (

// Hide Toggle When Terminal Here

); } }; ``` ### Data Attributes ```javascript { id: '[optional] string', name: 'string', children: '[optional] array', toggled: '[optional] boolean', active: '[optional] boolean', loading: '[optional] boolean', decorators: '[optional] object', animations: '[optional] object' }, ``` #### id The component key. If not defined, an auto-generated index is used. #### name The name prop passed into the Header component. #### children 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 Toggled flag. Sets the visibility of a node's children. It also sets the state for the toggle decorator. #### active Active flag. If active, the node will be highlighted. The highlight is derived from the `node.activeLink` style object in the theme. #### loading Loading flag. It will populate the treeview with the loading component. Useful when asynchronously pulling the data into the treeview. #### decorators / animations 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.
