Why can't we implement accordion?
<style>
.collapse-enter{
max-height: 0;
}
.collapse-enter-active {
max-height: 10rem;
-webkit-transition: all .3s cubic-bezier(1.0, 0.5, 0.8, 1.0);
transition: all .3s cubic-bezier(1.0, 0.5, 0.8, 1.0);

.collapse-leave {

}
.collapse-leave-active {
max-height: 0;
-webkit-transition: all .3s cubic-bezier(1.0, 0.5, 0.8, 1.0);
