React Super Treeview === :clap: Finally, a React Treeview component which is customizable on every level. Add/remove nodes, put your own animation, load data asynchronously, and even multi-select ## :star2: [See Demo w/ Example code](https://azizali.github.io/react-super-treeview/examples/) **Gif feature demo** ![alt text](./src-examples/everything.gif "Example") **`shift + click` multi-select gmail-style** ![alt text](./src-examples/multi-select.gif "Multi-select") ## Full Features - Expand/Collapse - Checkbox - Delete button - Provide custom delete button - Asynchronously load data - Provide custom loading indicator - Delete animation - Unlimited nesting - Granular control over when to show expand, checkbox or delete options - Multi-select/unselect checkbox (shift + Check) like Gmail - Control the node adding/delete animation speed ## How to install `npm install react-super-treeview --save` ## Basic Usage Start using the component in just 2 steps. ### Step 1: Import and use component in React: ```javascript import React from 'react'; import ReactDOM from 'react-dom'; import SuperTreeview from 'react-super-treeview'; class Example extends React.Component { constructor(){ super(); // SET YOUR DATA this.state = { data: [ { id: 1, name: 'Parent A' }, { id: 2, name: 'Parent B', isExpanded: true, isChecked: true, children: [ { id: 1, name: 'Child 1' }, { id: 2, name: 'Child 2' } ] } ] }; } render(){ return ( // RENDER THE COMPONENT { this.setState({data: updatedData}) }} /> ); } } ReactDOM.render(, document.getElementById('app');); ``` ### Step 2: Import styles to project Import SuperTreeview styles with `css` or `scss` file. The styles are in `node_modules/react-super-treeview/dist/style.css or style.scss` Note: When you use the `scss` file, you can modify the style variables for quick styling. #### Using webpack If you are using webpack, put this in your project's styles. ``` ~react-super-treeview/dist/style.css ``` or `scss` ``` ~react-super-treeview/dist/style.scss ``` the tilda `~` tells webpack to pick-up the file from `node_modules` folder #### Manually importing styles You can also manually copy the `css`/`scss` file from `node_modules/react-super-treeview/dist/style.(s)css` and put it in your project files ## All Props Required Props * Props | Type | Default | Description --- | --- | --- | --- `data` * | array | none | Data that will be displayed in the tree. `onUpdateCb` * | function | none | Function callback when data gets changed (deleted, expanded/collapsed, checked/unchecked). `depth` | number | `0` | Value that tracks the depth of the node tree. The root/highest depth is 0. Children nodes are depth+1 upto infinity. `deleteElement`| element | `

(X)

`| Element that displays as the delete button. `getStyleClassCb`| function | `(node, depth) => { return ' '; }` | Return the class name string you want to add on the node. `isCheckable`| function | `(node, depth) => { return true; }`| Return `true/false` to show/hide checkbox on node. `isDeletable`| function | `(node, depth) => { return true; }`| Return `true/false` to show/hide delete button on node. `isExpandable`| function | `(node, depth) => { return true; }`| Return `true/false` to show/hide expand/collapse button (►) on node. `keywordChildren`| string | `'children'`| Set the `key` where the component should look for the children elements. `keywordChildrenLoading`| string| `'isChildrenLoading'`|Set the `key` that indicates if the children nodes are loading or now. If `true` then the `loadingElement` is shown. NOTE: Make sure that the node is expanded (`isExpanded: true`) for the `loadingElement`. `keywordKey`| string | `'id'` | This is the value that is set as the `key` attribute on the node (`

node name

`). It defaults to the `id` key. This must be a unique key, if not provided or is not unique, will break the animation feature. `keywordLabel`|string|`'name'` | The node text is printed from the `name` key. If you want some other key value to be printed, provide the key here. `loadingElement`| element | `

`|Element that shows when data is being loading. Provide your custom loading element with this prop. `noChildrenAvailableMessage` | string | `'no data found'` |Message that shows when the expanded node has no children. `onCheckToggleCb`| function |`(arrayOfNodes, depth) => {}`|Function callback when checkbox gets toggled. The callback provides an array of nodes (`arrayOfNodes`) that got checked/unchecked. Since `` has a multi-select feature, hence its an array here. All nodes will have the same `isChecked` state, either `true` or `false`. The callback also provides the `depth` of the node that got checked/unchecked. `onDeleteCb`|function|`(node, updatedData, depth) => { return true; }`|Function callback when node delete button gets clicked. The callback provides the `node` being deleted, its `depth`, and the updated data (`updatedData`) with the deleted node removed. Return `true` if you want to proceed with the deletion, and `false` if you do not want to delete the node. Returning `true` will trigger the `onUpdateCb()` prop, discussed below. `onExpandToggleCb`|function| `(node, depth) => {}`|Function callback when node Expands/Collapses. The callback function provides the `node` that got toggled, and its `depth`. `transitionEnterTimeout`|number|`1200`|Time in milliseconds for node appear animation. `transitionExitTimeout`|number|`1200`|Time in milliseconds for node remove ## Data Format ``` [ { id: 1, name: 'Any String', isExpanded: true, isChecked: true, isChildrenLoading: false children: [ id: 2, name: 'Any String', isExpanded: true, isChecked: true, isChildrenLoading: true children: [] ] } ]; ``` ## Test ``` npm test ``` ## Shoutout Shoutout to [Andrew Onyshchuk](https://github.com/oandrew) for suggesting a clean API exposing strategy. Thank you [TJ Hubert](https://github.com/tjhubert) and [Prashanth Naika](https://github.com/pnaika) for your contribution to the animation feature and the bug fixes. ### TODO: - [X] Bug: `keywordKey` prop is not being applied - [ ] Feature: Make user friendly prop names for `keywordKey`, `keywordChildren` etc - [ ] Performance: Remove the need for lodash - [ ] Feature: Stretch goal: Add ability to add custom decorator/element per node - [ ] Feature: Add css class on nodes based on its state i.e `

Text

` - [X] Feature: Provide .scss file with configurable variables - [ ] Workflow: Provide auto-launch browser feature when examples are run with `npm run examples` ### License SuperTreeview is [MIT licensed](./LICENSE).
