The category of each list item can be mapped with groupBy field in the data table, which also supports single-level navigation.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ListViewModule } from '@syncfusion/ej2-angular-lists'




import { Component} from '@angular/core';

@Component({
imports: [
        
        ListViewModule
    ],


standalone: true,
    selector: 'my-app',
    template: `<ejs-listview id='sample-list' [dataSource]='data' [fields]='fields' ></ejs-listview>`
})

export class AppComponent {
    public data: Object = [
    {
        'text': 'Audi A4',
        'id': '9bdb',
        'category': 'Audi'
    },
    {
        'text': 'Audi A5',
        'id': '4589',
        'category': 'Audi'
    },
    {
        'text': 'BMW 501',
        'id': 'f849',
        'category': 'BMW'
    },
    {
        'text': 'BMW 502',
        'id': '7aff',
        'category': 'BMW'
    }
    ];

    public fields: Object = { groupBy: 'category', tooltip: 'text' };

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

The grouping header can be customized by using groupTemplate property for both inline and fixed group header.
