<div class="countries-list"> 
    <span class="countries-list__header">{{'GeneralOrganizationalBackgroundSurveyComponent-STEP_6_ALL_LOCATIONS' | translate}}</span> 
    <ul> 
     <li *ngFor="let country of filteredCountries" 
      (click)="selectCountry(country, 'add')" 
      class="add" 
      [ngClass]="{'selectedCountry': selectedCountry?.name == country.name && selectedCountry?.action === 'add', 
         'disabledSelection': selectedCountry?.disabledSelection && selectedCountry?.name == country.name}"> 
      {{ country.name }} 
     </li> 
    </ul> 
</div> 
<div class="contries-controllers"> 
    <a class="btn-floating btn waves-effect waves-light cyan darken-3" 
     [ngClass]="{'disabled': selectedCountry === null || selectedCountry?.action === 'delete'}" 
     (click)="addCountryFromForm(selectedCountry.code)"> 
     <i class="material-icons">add</i> 
    </a> 
</div> 

例えば、*ngIf指令の正確なユースケースのように思える:

<li *ngIf='!selectedCountries.includes(country.code)'
