Incorrect working collapse() method?

[Shurikkan]

I'm trying hide all active accordion panels and then show panel by ID.
Then, when I click on adjacent accordion panels - all panels are showing.

Here is example of code:

Сlick on the various panells and you will be able to see the problem.

P.S.: Sorry for my bad english :)

Support for v3 has mostly ceased. Please let us know if this issue affects v4.
See : #20631

Bootstrap 3

BS3 support is ceased because BS4 stable version is already appeared?

[Johann-S]

No because the team and folks wants to focus on the development of V4

[Shurikkan]

I try this in Bootstrap 4 (alpha):

and the result has not changed.

Code write in accordance with the official documentation on the website:
https://v4-alpha.getbootstrap.com/components/collapse/

Previous code version (on BS3):
https://getbootstrap.com/javascript/#collapse

Maby include this information in BS4 documentation?
I think it's a pretty useful thing!
