Is it possible to set select option disabled
, if the value is j = 0
?
The j value is taken from a DB.
<ng-container *ngFor="let interventi of variabileIntervento; index as i"> <tr *ngFor="let variante of interventi.varianti; index as j"> <td><select [(ngModel)]="type" (change)="changeTotal()"> <option selected disabled>Select</option> <option value="0">{{interventi.supIntonacate[j]}}</option> <option value="1">{{interventi.supEvIi[j]}}</option> <option value="2">{{interventi.supIvEi[j]}}</option></select></td>

Answer
Try this:
<option selected [disabled]="j === 0 ? true : false">Select</option>
or this, if not work:
<option selected [attr.disabled]="j === 0 ? 'disabled' : null">Select<option>
