简单使用

注意：transition 需配合 v-if / v-show使用

    <transition name="leftCompTransition" mode="out-in">
      <div class="choose-box" v-if="isShowBox"></div>
    </transition>

完整使用（案例）

    <transition name="leftCompTransition" mode="out-in">
      <div class="choose-box" v-if="isShowBox">外面的大盒子</div>
    </transition>

    <div :class="[isShowBox ? 'folding-box-show' : 'folding-box-hide', 'folding-box']"
         :title="isShowBox ? '收起' : '展开'"
         @click="changeIsShowBox"
    >
      <i :class="isShowBox ? 'el-icon-arrow-left' : 'el-icon-arrow-right'"></i>
    </div>


      isShowBox: true,
   
	changeIsShowBox() {
      this.isShowBox = !this.isShowBox;
    }
