How can I implement custom transitions using React Transition Group?

You can create custom transitions by using the CSSTransition component from React Transition Group. You can define your own CSS classes for entering and exiting states.

Can you show me an example of how to set that up?

Sure! First, install the package with npm install react-transition-group. Then, you can use it like this:

import { CSSTransition } from 'react-transition-group';

<CSSTransition
  in={show}
  timeout={300}
  classNames="fade"
  unmountOnExit
>
  <div className="my-component">Hello World!</div>
</CSSTransition>

Make sure to define the CSS for the fade class.

What CSS should I add for the fade effect?

You can add the following CSS:

.fade-enter {
  opacity: 0;
}
.fade-enter-active {
  opacity: 1;
  transition: opacity 300ms;
}
.fade-exit {
  opacity: 1;
}
.fade-exit-active {
  opacity: 0;
  transition: opacity 300ms;
}
