官网例子 <div class="block"> <span class="demonstration">hover 触发子菜单</span> <el-cascader v-model="value" :options="options" :props="{ expandTrigger: 'hover' }" 这样是不生效的 @change="handleChange"></el-cascader> </div> 应该写成下面这样
<div class="block"> <span class="demonstration">hover 触发子菜单</span> <el-cascader expand-trigger="hover" :options="options" v-model="selectedOptions2" @change="handleChange"> </el-cascader> </div
