Angular Material DatePicker: Month and Day Picker with Selector

问题

The following datepicker, has only Month and Day, with no year as intended. However, it does not have a Month selector as the picture below. How do I fix to allow a Month Picker, with no year? Trying to modify code from the question below .

It probably needs to be injected in the periodLabel row below.

<div class="example-header">
   <button mat-icon-button (click)="previousClicked('month')">
    <mat-icon>keyboard_arrow_left</mat-icon>
  </button>
  <span class="example-header-label">{{periodLabel}}</span> <!-- probably need to add code in this line -->
  <button mat-icon-button (click)="nextClicked('month')">
    <mat-icon>keyboard_arrow_right</mat-icon>
  </button>
</div>
