    Collect statistics on the use of open source

    TOAST UI Tree applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI Tree is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. > “") is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the following usageStatistics option when creating the instance.

    const options = {
     usageStatistics: false
    const instance = new Tree(container, options);

    Or, include tui-code-snippet(v2.3.0 or later) and then immediately write the options as follows:

    tui.usageStatistics = false;

    🔨 Usage


    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( ... );
