I want to implement something similar with angular-permisssion. And with requirement to control the element\'s existance, I need to use angular structural directive.
@Günter Zöchbauer answer is almost correct.
Actually right now to make his answer working you need to explicitly rename the secondary @Input name. So it should be:
@Input("permissionIfExcept") set permissionIfExcept(value: string) { this._except = value; console.log('except: ', value); }
