But what about within a MAPPED data array with keys

[DheerajVermagwd]

I am trying to do this in a functional component using useState hook. But it is adding the class to all the panels. It should add the class only on the clicked element. Please help Thanks...

Is there any reason why should I use this kind of way instead of just classList.toggle("")? Is it to keep the "react way"?

How to do it with ul list items? I mean when I click on one of the li I want to add class active on this element but remove (if there are any) from others li? You know, typical menu for example.. I'm new in React and try to solve this problem, but so far I didn't found a solution.
