Potrzebuje wybrać domyślnie z listy drugą jednostkę gdy pierwsza jest 'kpl'.Warunek umiem obsłużyć.Myślałem,że da radę zwykłym (change)="ChangingValue($event)" [value]='1' ale wtedy nie zmienia ceny.Nie siedzę w angularu i nie bardzo mi wychodzi zmiana kodu
<app-select *ngIf="productsList.products[i]?.units?.size > 1"
class="unit"
[(ngModel)]="productsList.products[i].unitId"
(ngModelChange)="productsList.unitConverter(i);">
<app-option *ngFor="let el of productsList.products[i].units | iterableToArray"
[value]="el[0]">
{{el[1].auxiliaryUnit}}
</app-option>
</app-select>
Metoda pobierająca jednostki tak mi się wydaje
/**

*/
