<hor-cell required label="请选择城市2" :value="result2" @click="handleOpen2" arrow />
<hor-picker :filterable="true" ref="horPickerInstance" />
<script setup lang="ts">
  import { HorCell, HorPicker } from '@daysnap/horn-ui'
  import type { HorPickerInstance } from '@daysnap/horn-ui'
  import { ref } from 'vue'

  const horPickerInstance = ref<HorPickerInstance>()
  const result = ref()
  const handleOpen = async () => {
