我需要在扩展内创建带有复选框的选择列表扩展面板

<mat-expansion-panel *ngFor="let item of Dataseource">
  <mat-expansion-panel-header style="display:flex" class="mat-row">
    {{datasource.showheader}}
  </mat-expansion-panel-header>
  <div *ngFor="let match of Datasource; let i= index">

                      <mat-selection-list  [(ngModel)]="selectedOptions" (ngModelChange)="onNgModelChange($event)">
                            <mat-list-option [value]="match">
                              <div class="container-name">
                                <div class="col-6">{{match.Name }}  vs {{ match.Address }}</div>
                              </div>
                              <mat-divider [inset]="true" *ngIf="!last"></mat-divider>
                            </mat-list-option>
                          </mat-selection-list>
    </div>
  </div>
