Angular Material - matIcon in MatSelect

Issue

I use this angular material select in my Angular 5 application:

<mat-form-field style="width:88%;">
    <mat-select placeholder="Contact *" formControlName="contact">
       <mat-option *ngFor="let contact of contacts" [value]="contact">
         <mat-icon [ngStyle]="{'color': contact.color}">home</mat-icon>{{contact.institution}} 
       </mat-option>
    </mat-select>
</mat-form-field>

On the select panel <mat-icon> are listed as expected but if I select one option then the home icon does not appear in <mat-form-field>

How could I also view the home icon in <mat-form-field> once selected?

Solution

This can be accomplished via the "mat-select-trigger" option. Documentation on the "mat-select" can be found here.

Below should be a working example of what you are trying to do. Based on what you provided.

<mat-form-field style="width: 88%">
  <mat-select placeholder="Contact *" formControlName="contact">
    <mat-select-trigger>
      <mat-icon>home</mat-icon>&nbsp;{{ contact.institution }}
    </mat-select-trigger>
    <mat-option *ngFor="let contact of contacts" [value]="contact">
      <mat-icon [ngStyle]="{ color: contact.color }">home</mat-icon>{{ contact.institution }}
    </mat-option>
  </mat-select>
</mat-form-field>

And apply styles as necessary.
