Set custom animation in React Accordion component

29 Aug 202316 minutes to read

Accordion supports custom animations for both expand and collapse actions from the provided animation option of Animation library. The animation property also allows you to set easing, duration, and various other effects of your choice.

Default animation is given as SlideDown for expanding the panel using expand animation property and SlideUp for collapsing the panel using collapse animation property. You can also disable the animation by setting animation effect as none.

The sample demonstrates some types of animation that suits for Accordion. You can check all the animation effects here.
