当然。最好的办法是限制你绑定的物品，如果长度超过你的最大值，就显示一个“更多”按钮。你也可以稍微做点手脚，像这样做：

// Component
maxItems = 5;
displayItems = this.maxItems;
data = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];

<!-- Template -->
<ng-container *ngFor="let item of data; let i = index">
  <div *ngIf="i < displayItems">Item {{ item }}</div>
</ng-container>

<div *ngIf="data.length > maxItems">
  <button type="button" (click)="displayItems = displayItems === maxItems ? 9999999 : maxItems">
    {{ displayItems === maxItems ? 'Show More' : 'Show Less' }}
  </button>
</div>
