This section explains how to create a simple DropDownButton and demonstrate the basic usage of the DropDownButton component in an Angular environment.
The list of dependencies required to use the DropDownButton component in your application is given below:
|-- @syncfusion/ej2-angular-splitbuttons
|-- @syncfusion/ej2-angular-base
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-splitbuttons
|-- @syncfusion/ej2-popups
|-- @syncfusion/ej2-buttonsYou can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.
npm install -g @angular/cliStart a new Angular application using below Angular CLI command.
ng new my-app
cd my-appTo install DropDownButton package, use the following command.
npm install @syncfusion/ej2-angular-splitbuttons --saveThe above package installs DropDownButton dependencies which are required to render the component in the Angular environment.
Import DropDownButton module into Angular application(app.module.ts) from the package
@syncfusion/ej2-angular-splitbuttons.
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// Imported Syncfusion dropdown button module from splitbuttons package.
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule, DropDownButtonModule ], // Registering EJ2 Dropdownbutton Module.
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }Modify the template in app.component.ts file to render the DropDownButton component.
import { Component } from '@angular/core';
import { ItemModel, MenuEventArgs } from '@syncfusion/ej2-angular-splitbuttons';
@Component({
selector: 'app-root',
template: `<!-- To render DropDownButton. -->
<button ejs-dropdownbutton [items]='items' content='Clipboard'></button>`
})
export class AppComponent {
// Initialize action items.
public items: ItemModel[] = [
{
text: 'Cut'
},
{
text: 'Copy'
},
{
text: 'Paste'
}];
}Add DropDownButton component’s styles as given below in style.css.
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";Run the application in the browser using the following command:
ng serveThe following example shows a basic Button component.
import { Component } from '@angular/core';
import { ItemModel } from '@syncfusion/ej2-angular-splitbuttons';
@Component({
selector: 'app-root',
template: `<!-- To render DropDownButton. -->
<button ejs-dropdownbutton [items]='items' content='Clipboard'></button>`
})
export class AppComponent {
// Initialize action items.
public items: ItemModel[] = [
{
text: 'Cut'
},
{
text: 'Copy'
},
{
text: 'Paste'
}];
}import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
/**
* Module
*/
@NgModule({
imports: [
BrowserModule,
DropDownButtonModule
],
declarations: [AppComponent],
bootstrap: [AppComponent]
})
export class AppModule { }import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
