As I know Astroid framework template One uses Bootstrap 4, So I copied Accordion example code from here getbootstrap.com/docs/4.5/components/col...e/#accordion-example to my article but while it works fine on their page where while opening second card first one closes and so on there is only one opened card everytime.
On my page there is problem with closing cards animation of closing goes on but then it opens by itself so I have two opened cards at a time.
you can check it here zugdidi.cobaltcck.com.ge/chven-shesaxeb
So when you open this page and click on Collapsible group item 2, it will close first and open second as it should be but when you click on another (no matter 1 or 3) it will leave second item opened and also open another one so you will have 2 items opened at a time as shown on image below
