I'm using my Angular project for Angular material Year Month picker. Anyone has some idea how to show only Year for the pick.
.html
<mat-form-field appearance="fill">
<mat-label>Month and Year</mat-label>
<input matInput [matDatepicker]="dp" [formControl]="date">
<mat-datepicker-toggle matSuffix [for]="dp"></mat-datepicker-toggle>
<mat-datepicker #dp
startView="multi-year"
(yearSelected)="chosenYearHandler($event)"
(monthSelected)="chosenMonthHandler($event, dp)"
panelClass="example-month-picker">
</mat-datepicker>
</mat-form-field>
.ts
import {Component} from '@angular/core';
import {FormControl} from '@angular/forms';
import {MomentDateAdapter, MAT_MOMENT_DATE_ADAPTER_OPTIONS} from '@angular/material-moment-adapter';
import {DateAdapter, MAT_DATE_FORMATS, MAT_DATE_LOCALE} from '@angular/material/core';
import {MatDatepicker} from '@angular/material/datepicker';
// Depending on whether rollup is used, moment needs to be imported differently.
// Since Moment.js doesn't have a default export, we normally need to import using the `* as`
// syntax. However, rollup creates a synthetic default module and we thus need to import it using
// the `default as` syntax.

MY_FORMATS dateInput as YYYY to display year only.NG_VALUE_ACCESSOR and the multi-provider to extend existing providers. (Refer to References 2)ControlValueAccessor to the component to integrate the custom form control value with Angular Reactive Forms. (Refer to References 2 & 3)datepicker-views-selection-example.html
