I’m using angular 13, and I have a mat-select that uses a ngx-mat-select-search with a noEntriesFoundLabel that is supposed to display a label when there are no options available for the mat-select.

My issue is that i’m using a <mat-option >-</mat-option> with no value, that is supposed to serve as a “all” value.

  <mat-form-field>
    <mat-select [formControl]="bankCtrl" placeholder="Bank" #singleSelect>
      <mat-option>
        <ngx-mat-select-search [noEntriesFoundLabel]="'No options'" [formControl]="bankFilterCtrl"></ngx-mat-select-search>
      </mat-option>

      <mat-option >-</mat-option>
      <mat-option *ngFor="let bank of filteredBanks | async" [value]="bank">
        {{bank.name}}
      </mat-option>
    </mat-select>
  </mat-form-field>

Because of this, when there is not matching option with the user’s input, the no-match-label is not displayed because there is still this “-” option available.

Basically what I need is a kind of “offset” so that the noEntriesFoundLabel is displayed when there is only one match (my default “-“)
I didn’t find such a feature.

Do you have any kind of workaround I could use?
