    <span class="caret"></span>

    <li><a href="#">Something else here</a></li>
    <li role="separator" class="divider"></li>

<select [(ngModel)]="whereWeStoreTheValue">
  <ng-container *ngFor="let option of options">
    <option *ngIf="!option.isDivider" [ngValue]="option">{{option.name}}</option>
    <option *ngIf="option.isDivider" disabled>{{option.name}}</option>

  </ng-container>
</select>

class MyComponent {
  options = [
   {name: 'Action'}, 
   {name: 'Another action'},
   {name: 'Something else here'},
   {isDivider: true},
   {name: 'Separated link}
  ];
}
