The HTML Content Template () element is a mechanism for holding HTML that is not to be rendered immediately when a page is loaded but may be instantiated subsequently during runtime using JavaScript.

Your browser does not support the audio element. Whenever I read about working with DOM in Angular I always see one or few of these classes mentioned: ElementRef ...

I want to dynamically add components to a container, and then change the some properties via componentRef.instance, Sometime i have to merge some compoents to one and change some properties again ...
