Installation

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-dropdowns

Manual Setup

All components that you reference during the installation will be present in the final bundle of your application. To avoid ending up with components you do not actually need, either:

  • Import all Dropdowns components at once by using the DropDownsModule, or
  • Import a specific Dropdowns component by adding it as an individual NgModule.

  1. Download and install the package.

        npm install --save @progress/kendo-angular-dropdowns @progress/kendo-angular-l10n @progress/kendo-angular-popup @progress/kendo-angular-treeview @progress/kendo-angular-inputs @progress/kendo-angular-intl @progress/kendo-drawing @progress/kendo-angular-common @progress/kendo-licensing

  2. Once installed, import the NgModule of the components you need.

    To get all package components, import the DropDownsModule 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 { DropDownsModule } from '@progress/kendo-angular-dropdowns';
import { AppComponent } from './app.component';

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

    The package also exports the following modules for individual components:

    • AutoCompleteModule

    • ComboBoxModule

    • DropDownListModule

    • DropDownTreeModule

    • MultiColumnComboBoxModule

    • MultiSelectModule

      To reduce the size of your application, include only the ones you need.

      import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';

// Imports the AutoComplete module
import { AutoCompleteModule } from '@progress/kendo-angular-dropdowns';

// Imports the ComboBox module
import { ComboBoxModule } from '@progress/kendo-angular-dropdowns';

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

  3. You are required to install one of the Kendo UI themes for Angular to style your components. For more information on how to add the styles, refer to the section on styling.

  4. For Angular 9.x and later, install the @angular/localize package:

    1. Run npm install --save @angular/localize.
    2. Add import '@angular/localize/init'; to your src/polyfills.ts file.

  5. 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.

  • @angular/common
  • @angular/core
  • @angular/forms
  • @progress/kendo-angular-common
  • @progress/kendo-angular-l10n
