I am using angular cli version - 11.2.8 and using the ng-select version of 7.3. Currently, I am able to render the UI as expected but when I tried to search in the input box inside the select element, it didn't search anything. I look for the issue in the package detail of NPM itself then have a list of versions which are compatible with different kinds of angular CLI version. Looks like I am using the correct version, still ng-select not working as properly.

<ng-select [(ngModel)]="selectedCars">
   <ng-option *ngFor="let car of cars" [value]="car.id">{{car.name}}</ng-option>
</ng-select>

 selectedCars = 3; //i also used selectedCars =[3], and selectedCars ="3", but it didn't work
  cars = [
    { id: 1, name: 'Volvo' },
    { id: 2, name: 'Saab'},
    { id: 3, name: 'Opel' },
    { id: 4, name: 'Audi' },
];
