添加ul inside p标记时角度模板解析错误

我正在开发演示项目,工作很好,如果我不添加UL标签内的P标签。

工作代码:

<p>
<br/> Umesh test help <br/>
</p>
<ul>
<li *ngFor="let user of help2Listdata">
    <a routerLink="/details/{{user.hid}}">{{ user.hid }}</a>

    <ul>
        <li><a href="http://{{ user.name }}">{{ user.name }}</a></li>
        <li>{{ user.ans }}</li>
    </ul>
</li>
</ul> 

<p>
<br/> Umesh test help <br/>

<ul>
    <li *ngFor="let user of help2Listdata">
        <a routerLink="/details/{{user.hid}}">{{ user.hid }}</a>

        <ul>
            <li><a href="http://{{ user.name }}">{{ user.name }}</a></li>
            <li>{{ user.ans }}</li>
        </ul>
    </li>
</ul>
</p>

请让我帮助你理解我为什么要面对这个问题。当我在inspect模式下看到工作代码输出时,它看起来很好,但是当更改标记树结构时,它会在浏览器控制台中抛出上面的错误。
