Either use the quick setup (Angular CLI) or manually add the package.

Quick Setup with Angular CLI

Angular CLI supports the addition of packages through the ng add command which executes in one step the set of otherwise individually needed commands.

    ng add @progress/kendo-angular-treeview

Manual Setup

  1. Download and install the package.

       npm install --save @progress/kendo-angular-treeview @progress/kendo-angular-common @progress/kendo-angular-inputs @progress/kendo-angular-intl @progress/kendo-angular-l10n @progress/kendo-angular-popup @progress/kendo-drawing @progress/kendo-licensing
  2. Once installed, import the TreeViewModule in your application root or feature module.

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
    import { TreeViewModule } from '@progress/kendo-angular-treeview';
    import { AppComponent } from './app.component';
        bootstrap:    [AppComponent],
        declarations: [AppComponent],
        imports:      [BrowserModule, BrowserAnimationsModule, TreeViewModule]
    export class AppModule {
  3. You are required to install one of the Kendo UI themes for Angular to style your component. For more information on how to add the styles, refer to the section on styling.

  4. Follow the instructions on the Kendo UI for Angular My License page to activate your license. You can skip this step if your application already contains a Kendo UI license file.


The TreeView package requires you to install the following peer dependencies in your application:

  • @angular/animations
  • @angular/common
  • @angular/core
  • @progress/kendo-angular-common
  • @progress/kendo-angular-inputs
  • @progress/kendo-angular-intl
  • @progress/kendo-angular-l10n
  • @progress/kendo-angular-popup
  • @progress/kendo-drawing
  • @progress/kendo-licensing
  • rxjs

The TreeView package utilizes the Angular animation system, which supports a specific set of browsers.

Functionality and Features

Due to the implementation logic of its functionality, the TreeView is a highly flexible and customizable component that supports n number of levels.

The default behavior for rendering the node structure of its data as well as the implementation of the data binding, drag and drop, selection, checkboxes, disabled and expanded state features is controlled by specific individual options and self-contained directives.

At the same time, however, the architectural approach behind the component allows the complete overriding of its built-in behavior by fully replacing the default implementations with custom code.

You can also use a context menu in the TreeView by integrating the Kendo UI ContextMenu for Angular.
