is it possible to be an accordion item expanded when the component is shown?
Great Tutorial.
The only problem I am having is that my application is not loading and stays in a white screen because of the following error in the console log. I am importing it correctly into the app.module.ts file.
This is the error I am getting.

Loved the document, i used it and its working so nicely, meeting all the defined requirements

One question, how can you add a "hat" to the accordion as per the image?

Thanks, this is a very useful bit of code. I was not able to get it working with ngFor to populate items. If it should work is there a sample?
