            <li>Read</li>
            <li>Help</li>
            <li>About</li>
        </ul>   
    </div>
    <div>
        <input type="button" ej-button id="drawerTarget" text="Open Drawer" style="top:200px;left:400px;position:absolute" />
    </div>

ts

export class AppComponent {
        enablelistview: any;
        listviewsettings: any;
        constructor() {
            this.enablelistview = true;
            this.listviewsettings = { height: 500 };
        }
