I Need to add the mask '000.000.000-00' for each data added.. Can someone help-me?

I tryed to add mask="000.000.000-00" but not ok.

If you are trying to add a mask to the ng-select element, it is not possible to do so directly with the mask attribute. The ng-select element does not have a built-in masking feature.

One way to add a mask to the ng-select element is to use a third-party library that provides a masking feature, such as ngx-mask or angular2-text-mask. You can then use the masking feature provided by the library to add the mask to the ng-select element.

Here is an example of how you can use the ngx-mask library to add a mask to the ng-select element:

Install the ngx-mask library by running the following command:

npm install ngx-mask

Import the NgxMaskModule in your Angular module where you want to use the ng-select element.

import { NgxMaskModule } from 'ngx-mask';

@NgModule({
  // other module imports
  imports: [
    // other imports
    NgxMaskModule.forRoot()
  ]
})

Use the [mask] attribute to add the mask to the ng-select element. The value of the [mask] attribute should be the mask that you want to use. In your case, the mask should be 000.000.000-00.

<ng-select [mask]="'000.000.000-00'" [multiple]="true" [addTag]="addTag" id="fieldId"
           [ngClass]="formValidatorHelper.applyCssError(MyService.form.controls['fieldId'])"
           formControlName="fieldId">
</ng-select>

I hope this helps!

-- Correction as per your comment -- The error message "Can't bind to 'mask' since it isn't a known property of 'ng-select'" indicates that the ng-select element does not have a property named 'mask'. This is because the ng-select element does not have a built-in masking feature, and the [mask] attribute is not a native attribute of the ng-select element.

To fix this error, you need to use a third-party library that provides a masking feature for the ng-select element. For example, you can use the ngx-mask library, which provides a mask attribute that you can use with the ng-select element.

To use the ngx-mask library, follow these steps:

Install the ngx-mask library by running the following command:

npm install ngx-mask
Import the NgxMaskModule in your Angular module where you want to use the ng-select element.
Copy code
import { NgxMaskModule } from 'ngx-mask';

@NgModule({
  // other module imports
  imports: [
    // other imports
    NgxMaskModule.forRoot()
  ]
})

Use the [mask] attribute to add the mask to the ng-select element. The value of the [mask] attribute should be the mask that you want to use. In your case, the mask should be 000.000.000-00.

<ng-select [mask]="'000.000.000-00'" [multiple]="true" [addTag]="addTag" id="fieldId"
           [ngClass]="formValidatorHelper.applyCssError(MyService.form.controls['fieldId'])"
           formControlName="fieldId">
</ng-select>

After importing the NgxMaskModule and using the [mask] attribute, the ng-select element should have a masking feature that you can use to add a mask to the element. This should resolve the error message that you are seeing.

To add a mask to an ng-select element in Angular, you can use the ngx-mask library. This library provides a directive that you can use to add a mask to any input element, including an ng-select element.

Here is an example of how to use the ngx-mask directive to add a mask to an ng-select element:

<!-- Import the ng-select and ngx-mask modules -->
import { NgSelectModule } from '@ng-select/ng-select';
import { NgxMaskModule } from 'ngx-mask';

@NgModule({
  imports: [
    // ...
    NgSelectModule,
    NgxMaskModule.forRoot()
  ],
  // ...
})
export class AppModule { }

<!-- Use the ng-select and ngx-mask directives in your component template -->
<ng-select [items]="items" [mask]="'00-00-0000'">

In the example above, we import the NgSelectModule and NgxMaskModule and add them to the imports array of the AppModule. We then use the ng-select and ngx-mask directives in the component template to create an ng-select element with a mask applied.

You can customize the mask by setting the mask attribute on the ng-select element. In the example above, we use the mask "00-00-0000", which will require users to enter a date in the format "MM-DD-YYYY". You can use any mask pattern supported by the ngx-mask library.
