[akanzari]

How can i make #wizard dynamic, for example my target will be #wizard{{i}}

<ng-container *ngFor="let activityId of (activityIds$ | async); let i = index;">
    <aw-wizard #wizard>
        <aw-wizard-step [stepTitle]="'Saisie A'"></aw-wizard-step>
        <aw-wizard-step [stepTitle]="'Saisie B'"></aw-wizard-step>
        <aw-wizard-step [stepTitle]="'En validation'"></aw-wizard-step>
    </aw-wizard>
</ng-container>
