Angular version of Accordion doesn't work

[AnassL]

Accordion #1

It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element.

Accordion #2

It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element.

Accordion #3

It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element.

The above is the simplest sample from the Angular version of Accordion documentation. I followed the instructions for the installation, but was not able to get the second, and third item content to show after clicked their relative buttons.

How to fix this, please ?
