在下拉选中以后触发事件，怎么设置呢？

后台

下拉框

<FormItem
    :label="t('auth.admin.grouping')"
    v-model="baTable.form.items!.group_arr"
    prop="group_arr"
    type="remoteSelect"
    :key="'group-' + baTable.form.items!.id"
    :input-attr="{
        multiple: false,
        params: { isTree: true, absoluteAuth: adminInfo.id == baTable.form.items!.id ? 0 : 1 },
      field: 'name',
      remoteUrl: '/admin/auth.Group/index',
      placeholder: t('Click select'),
  }"
  @change="groupAdmin"
/>

const groupAdmin = (e) => {
  console.log(e);
}
