    Hi @optixdev,

    1. You can check one of the existing pages to see how we use required field validation. You can take a look at role creation modal.
    2. Power Tools allows you to select a property named required when you are defining a field. So, it is very easy.

    <input id="RoleDisplayName" #roleNameInput="ngModel" class="form-control" type="text" name="DisplayName" [(ngModel)]="role.displayName" required maxlength="64">

    <validation-messages [formCtrl]="roleNameInput"></validation-messages>

    So, we have to use only "#roleNameInput="ngModel"" in <validation-messages [formCtrl]="roleNameInput"></validation-messages> ?

    Hi,

    I hven't tried this but it seems like there is an open issue on PrimeNG's GitHub repository, see https://github.com/primefaces/primeng/issues/3308. If it doesn't work, you can check the value in TypeScript code and display a message accordingly.
