Binding select element to object in Angular

This could help:

<select [(ngModel)]="selectedValue">
  <option *ngFor="#c of countries" [value]="c.id">{{c.name}}</option>
</select>

<h1>My Application</h1>
<select [(ngModel)]="selectedValue">
  <option *ngFor="let c of countries" [ngValue]="c">{{c.name}}</option>
</select>

StackBlitz example

NOTE: you can use [ngValue]="c" instead of [ngValue]="c.id" where c is the complete country object.

[value]="..." only supports string values
[ngValue]="..." supports any type

update

If the value is an object, the preselected instance needs to be identical with one of the values.

<select [compareWith]="compareFn" ...

Take care of if you want to access this within compareFn.

compareFn = this._compareFn.bind(this);

// or 
// compareFn = (a, b) => this._compareFn(a, b);

_compareFn(a, b) {
   // Handle compare logic (eg check if unique ids are the same)
   return a.id === b.id;
}
