'use client';

    </TransitionGroup>
  </div>

) }

index.scss

.animation { position: relative; overflow: hidden; transition: height 400ms ease; }

.transition>* { top: 0; left: 0; width: 100%; position: absolute; }

.page-transition-enter, .page-transition-appear { transform: translateX(100%); transition: none; }

.return .page-transition-enter, .return .page-transition-appear { transform: translateX(-100%); }

.page-transition-enter-active, .page-transition-appear-active { transform: translateX(0%) !important; transition: all 400ms cubic-bezier(0.25, 0, 0, 1); }

.page-transition-exit { transform: translateX(0); transition: none; }

.page-transition-exit-active { transform: translateX(-100%); transition: all 400ms cubic-bezier(0.25, 0, 0, 1); }

.return .page-transition-exit-active { transform: translateX(100%); transition: all 400ms cubic-bezier(0.25, 0, 0, 1); } }

Run the code above to see the results，Can you see if there's a configuration wrong？
