I have run into an issue in pre-selecting values on a dropdown list in Angular 2.
I set an array of colours in the component which I bind successfully to the drop
In the Component:
this.formGroup.patchValue({
preferredBankAccountId: object_id_to_be_pre_selected
});
You can also give this value where you initialize your formGroup or later,depending on your requirement.
You can do this by using [(ngModel)] binding also where you don't have to initialize your formControl.
Here, matchedCity is one of object within cities.
