TOAST UI products are available over the CDN powered by NHN Cloud.

Add the container element to create the component. A wrapper element should have tui-tree-wrap as a class name to apply tui-tree's style.

<div id="tree" class="tui-tree-wrap"></div>


This can be used by creating an instance with the constructor function. To get the constructor function, you should import the module using one of the following ways depending on your environment.

Using namespace in browser environment
const Tree = tui.Tree;
Using module format in node environment
const Tree = require('tui-tree'); /* CommonJS */
import Tree from 'tui-tree'; /* ES6 */

You can create an instance with options and call various APIs after creating an instance.

const container = document.getElementById('tree');
const instance = new Tree(container, { ... });

instance.add( ... );
