In my case I'm using a `formcontrolName` with the `mat-select`. I would like to display a value on the `mat-select`, but not inside the dropdown list of options :

```html
<mat-select #objet formControlName="cars" >
   <mat-option *ngFor="let f of listCars" [value]="f">{{f.name}}</mat-option>
</mat-select>

```

Thanks for helping!
