can anybody please help me to implement search filter with mat-select component in my application?

I found the solution for searching the dropdown values

Here is the html code

<mat-select class="yourClass" [(ngModel)]="searchObj">
            <input class="yourClass" placeholder ="search " (keyup)="onKey($"> 
            <mat-option *ngIf="someCondition" [value]='Select'>Select</mat-option>
            <mat-option *ngFor="let data of dataArray" [value]="data">{{data}}</mat-option>

Here is the typescript code key function getting the entered value

    onKey(value) { 
            this.dataArray= []; 

performing the searching given value inside the provided values in dropdown

            let filter = value.toLowerCase();
            for ( let i = 0 ; i <; i ++ ) {
                let option =[i];
                if ( >= 0) {
                    this.dataArray.push( option );

this function is goes where your main search function calling api and getting the data

            for ( let i = 0 ; i <; i ++ ) {
                this.dataArray.push([i] );
