TreeView Overview

The TreeView visualizes a hierarchical list.

Basic Usage

The following example demonstrates the TreeView in action.

import { Component } from '@angular/core';
@Component({
    selector: 'my-app',
    template: `
    <kendo-treeview
        [nodes]="data"
        textField="text"
        kendoTreeViewExpandable
        kendoTreeViewSelectable
        kendoTreeViewHierarchyBinding
        childrenField="items"
    >
    </kendo-treeview>
  `
})
export class AppComponent {
    public data: any[] = [
        {
            text: 'Furniture', items: [
                { text: 'Tables & Chairs' },
                { text: 'Sofas' },
                { text: 'Occasional Furniture' }
            ]
        },
        {
            text: 'Decor', items: [
                { text: 'Bed Linen' },
                { text: 'Curtains & Blinds' },
                { text: 'Carpets' }
            ]
        }
    ];
}

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';

@NgModule({
  bootstrap:    [ AppComponent ],
  declarations: [ AppComponent ],
  imports:      [ BrowserModule, BrowserAnimationsModule, TreeViewModule]
})
export class AppModule { }

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './ng.module';

enableProdMode();

const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);

Installation

Either use the quick setup (Angular CLI v6 or later) or manually add the package (Angular CLI v5 or earlier).

Quick Setup with Angular CLI v6 or Later

Angular CLI v6 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
  2. For Angular 6, install the rxjs-compat package. For more information, refer to the article on upgrading to Angular 6.

    npm install --save rxjs-compat@6

    For Angular 5 or earlier, install RxJS v5.5+.

    npm install --save rxjs@^5.5
  3. Once installed, import the TreeViewModule in your application root 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';
    
    @NgModule({
       bootstrap:    [AppComponent],
       declarations: [AppComponent],
       imports:      [BrowserModule, BrowserAnimationsModule, TreeViewModule]
    })
    export class AppModule {
    }
  4. 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 article on getting started.

Dependencies

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

  • @angular/animations
  • @angular/common
  • @angular/core
  • rxjs

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