how can i add an image on ion-option?
i try to list countries with flags, something like this

<ion-select [(ngModel)]="country" (ngModelChange)="changeCountry(country)" >
    <ion-option class="customOption" *ngFor="let c of countries" [value]="c.name">
        <img src="assets/img/flags/{{c.code | lowercase }}.png" width="57" height="35">
        {{ c.name }}
    </ion-option>
</ion-select>

but this doesn’t work
