not enough space in <mat-select>. How to add multiple line <mat-option>?

Issue

I want to have under the option text additional lines which describe the option. By default mat-select limits number of characters and add "..." at the end of the line. I want to have multiple line option of needed. stakckblitz demo: https://stackblitz.com/edit/angular-wj9svw My code:

export class SelectOverviewExample {
  foods: Food[] = [
    {value: 'steak-0', viewValue: 'Steak longDescription longDescription longDescription longDescription longDescription'},
    {value: 'pizza-1', viewValue: 'Pizza longDescription longDescription longDescription longDescription longDescription longDescription v v longDescription'},
    {value: 'tacos-2', viewValue: 'Tacos'}
  ];
}

html:

<mat-form-field>
  <mat-select placeholder="Favorite food">
    <mat-option *ngFor="let food of foods" [value]="food.value">
      {{food.viewValue}}
      <b> some additional text text text text texttext </b>
    </mat-option>
  </mat-select>
</mat-form-field>

Solution

Use following css :

    .mat-select-panel mat-option.mat-option {
      height: unset;
    }

   .mat-option-text.mat-option-text {
      white-space: normal;
    }

OR

/deep/ .mat-select-panel mat-option.mat-option {
  height: unset;
}

/deep/ .mat-option-text.mat-option-text {
  white-space: normal;
}
