Quick Start with Tree

This tutorial will walk you through creating a basic application containing Tree. You will learn how to initialize a Tree, populate it with data and set the desired configuration.

The final code of the tutorial can be used as the start point while creating applications using Tree.

A new HTML file and related code files

To start, create a new HTML file and include the related Webix code files in it.

Required code files are:

  • webix.css
  • webix.js

A basic html page with the included code files

<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Quick start with Tree</title>
    <script src="../codebase/webix.js" type="text/javascript" charset="utf-8"></script>
    <link rel="stylesheet" href="../codebase/webix.css" type="text/css" 
        charset="utf-8">
</head>
<body>
    <script>
        //here you will place your JavaScript code
</script> </body> </html>

Object constructor

After you have included the necessary files, you can move to Tree initialization.
To create a new Tree object you need to use the next constructor:

Tree constructor

webix.ui({ 
    view:"tree" 
});

In fact, it's enough to initialize a Tree. However, it's also possible to put a tree inside of an HTML container.

Placing Tree on a page

To set a tree in a particular position of a page, you can put it in a container. For that, you should create a div container. Let's create a container with the "box" id:

<div id="box" style="width:400px;height:200px;"></div>

After that you need to use the above mentioned Tree constructor and specify the created container via the corresponding property:

Basic Tree configuration

webix.ui({
    container:"box",
    view:"tree"
});

Loading data

There are different ways to load data into Tree (read about them in chapter Loading Data into Tree ).

We will use the easiest of the ways and specify data directly in the constructor with the help of the data property:

Loading data into the tree

webix.ui({
    // container:"box",
    view:"tree",
    data: [
        {id:"root", value:"Cars", open:true, data:[
            { id:"1", open:true, value:"Toyota", data:[
                { id:"1.1", value:"Avalon" },
                { id:"1.2", value:"Corolla" },
                { id:"1.3", value:"Camry" }
            ]},
            { id:"2", open:true, value:"Skoda", data:[
                { id:"2.1", value:"Octavia" },
                { id:"2.2", value:"Superb" }
            ]}
        ]}
    ]
});

Congratulations! Now you can run your app and it'll produce Tree shown at the very beginning.
