angular 2如何在* ngfor循环中创建多个标签？

Question

<div  *ngFor="let post of posts ;let i = index " >
    <div class="tabs_main">
        <ul class="tabs_ul">
            <li class="tabs_li active" (click)="explore_tab_one(post.id)"> Questions </li>
            <li class="tabs_li" (click)="explore_tab_two(post.id)"> Opinions</li>
        </ul>
        <div class="tab_content active">
            <div class="row">
                <div class="col-sm-12">
                    <h3> Tab 1 </h3>
                </div>
            </div>
        </div>
        <div class="tab_content">
            <div class="row">
                <div class="col-sm-12">
                    <h3> Tab 2 </h3>
                </div>
            </div>
        </div>
    </div>
</div>

如何在* ngfor循环中创建多个标签？

我的期望是点击意见，显示标签2并切换活动的类，只有第一个循环
