Can't have multiple template bindings on one element. Use only one attribute prefixed with 에러 해결

<div>
    <a *ngFor="let menu of menus" [routerLink]="menu.path" class="flex flex-col" (click)="handleMenuClick(menu)">
        {{ menu.name }}
        <ng-container *ngIf="menu.children && (currentPath == menu.path)">
            <a *ngFor="let item of children">
                {{ item.name }}
            </a>
        </ng-container>
    </a>
</div>

1. 태그 안에 *ngIf 와 *ngFor 같이 사용해서 발생

2. ng-container 를 활용하여 해결
