我在我的 mat-select 中使用 mat-expansion-panel。我第一次打开mat-select,没关系。但是当我点击mat-select关闭mat-select 并点击mat-select第二次重新打开它时,我mat-expansion-panel的已关闭,我必须双击才能打开它,但不能单击重新打开 mat-expansion-panel。你能帮助我吗?谢谢 !

<mat-select multiple [formControl]="formControl">
 <mat-expansion-panel *ngFor="let group of groups" [expanded]="true">
                <mat-expansion-panel-header>
                    <mat-panel-title title="{{group.name}}">
                        <mat-checkbox (click)="toggleGroupParent($event, group.name, group.selected)" [(ngModel)]="group.selected" >
                            {{group.name}}
                        </mat-checkbox>
                    </mat-panel-title>
                </mat-expansion-panel-header>
                <ng-container *ngFor="let item of items">
                    <mat-option *ngIf="item.type == group.name" [value]="item" (click)="togglePerOneInType(group.name)" title="{{item.text}}">
                        {{item.text}}
                    </mat-option>
                </ng-container>
            </mat-expansion-panel>
