Quick Start Example

import { ListViewModule } from '@syncfusion/ej2-angular-lists';
import { Component } from '@angular/core';

@Component({
  imports: [ListViewModule],
  standalone: true,
  selector: 'app-root',
  template: `
    <ejs-listview 
      id='sample-list' 
      [dataSource]='data'>
    </ejs-listview>
  `
})
export class AppComponent {
  // Simple string data
  public data: string[] = [
    'Artwork', 'Abstract', 'Modern Painting', 
    'Ceramics', 'Animation Art', 'Oil Painting'
  ];
}

CSS Import (in styles.css):

@import "../node_modules/@syncfusion/ej2-base/styles/material3.css";
@import "../node_modules/@syncfusion/ej2-angular-lists/styles/material3.css";

Run:

npm install @syncfusion/ej2-angular-lists --save
ng serve --open

Common Patterns

Pattern 1: Data-Driven List with Field Mapping

Use when displaying complex objects with multiple properties:

public data = [
  { name: 'John', email: '[e-mail]', id: '1' },
  { name: 'Jane', email: '[e-mail]', id: '2' }
];
public fields = { text: 'name', id: 'id' };

Pattern 2: Grouped List

Use when organizing items by category:

public fields = { text: 'name', groupBy: 'department' };

Pattern 3: Templated List

Use when you need custom layouts:

<ejs-listview [dataSource]='data' cssClass='e-list-template'>
  <ng-template #template let-data="">
    <div class="e-list-wrapper">
      <span>{{ data.name }}</span>
    </div>
  </ng-template>
</ejs-listview>

Pattern 4: Selection with Checkboxes

Use when users need to select multiple items:

<ejs-listview [dataSource]='data' [showCheckBox]='true'></ejs-listview>

Pattern 5: Dynamic Add/Remove

Use for interactive list management:

addItem() {
  this.listview.addItem([{ text: 'New Item', id: 'new' }]);
}
removeItem(element: HTMLElement) {
  this.listview.removeItem(element);
}
