Initialization

info

Download the DHTMLX Tree package:

To initialize DHTMLX Tree on a page, you need to take the following simple steps:

<!DOCTYPE html>
<html>
    <head>
        <title>How to Start with DHTMLX Tree</title>         
        <script type="text/javascript" src="../../codebase/tree.js"></script>
        <link rel="stylesheet" href="../../codebase/tree.css">
    </head>
    <body>
        <div id="tree_container"></div>
        <script>
            // creating DHTMLX Tree
            const tree = new dhx.Tree("tree_container",{
                // config options
            });
        </script>
    </body>
</html>

Include source files​

Unpack the downloaded package into a folder of your project.

After that, create an HTML file and place full paths to JS and CSS files of DHTMLX Tree into the header of the created file. The Tree component can be used standalone or as a part of the Suite library.

If you use DHTMLX Tree standalone, you need to include 2 files:

  • tree.js
  • tree.css
<script type="text/javascript" src="../../codebase/tree.js"></script>
<link rel="stylesheet" href="../../codebase/tree.css">

If you use DHTMLX Tree as a part of the Suite package, you need to include JS/CSS files of the dhtmlxSuite library:

  • suite.js
  • suite.css
<link type="text/css" href="../codebase/suite.css">
<script src="../codebase/suite.js" type="text/javascript"></script>

Create a container​

Add a container for Tree and give it an id, for example "tree_container":

index.html
<div id="tree_container"></div>

Initialize Tree​

Initialize Tree with the dhx.Tree object constructor. The constructor has two parameters:

  • the HTML container for Tree,
  • optional, an object with configuration properties. If this argument is not passed to the constructor, the settings will be default.
index.js
// creating DHTMLX Tree
const tree = new dhx.Tree("tree_container", {
    checkbox: true
});

Configuration properties​

There is a set of properties you can specify for Tree to optimize its configuration for your needs.

See the detailed information on configuration properties of Tree in the Tree API overview article.

Detailed information on loading data into Tree is given in the Data loading article.
