ElementUI

label 为空的不展示

将children设为undefined

dg(list) {list.forEach(item => {item.label = item.nameitem.value = item.iditem.children = item.childrenList.length !== 0 ? item.childrenList : undefinedif (item.children) {this.dg(item.children)}})
},

第一层不展示checkbox复选框

<el-cascaderpopper-class="device_cascader":options="options":props="props"clearable
></el-cascader>

<style lang="scss" scoped>
</style><style lang="scss">
.device_cascader {.el-cascader-panel {.el-scrollbar:first-child {.el-checkbox {display: none;}}}
}
</style>
