I am having a problem with disabling the add chip functionality.
After adding this to my code:
<p-chips name="tags" [disabled]="true" [(ngModel)]="model.tags"></p-chips>
The old chips are disabled (I can't remove them), however the input is still present and I can add new ones. Is there a way to disable this as well? Also is there a way to disable only a subset of the chips and not all of them?
