<van-tree-select v-model:active-id="activeId" v-model:main-active-index="activeIndex" :items="items" :field-names="{ text: 'name', children: 'children', value: 'id'}"

而且只能展示两级数据，无法展示第三级

[YunZhaoWang]

TreeSelect组件的确是二级 没有实现递归展示 这不是组件的bug ，你的仓库代码拉下来 这样基本能实现

<template>
    <van-tree-select 
        v-model:active-id="activeId" 
        v-model:main-active-index="activeIndex" 
        :items="treeData"
        @click-nav="changeCity">
            <template #content>
                <van-tree-select
                    v-model:active-id="activeChildrenId"
                    v-model:main-active-index="activeChildrenIndex"
                    :items="treeChildren"
                    @click-item="changeCity"
                />
         </template>
    </van-tree-select>
</template>
<script setup lang="ts">
  const treeChildren = ref([])
  const activeChildrenId = ref()
  const activeChildrenIndex = ref()
  const changeCity = (event) => {
      const item = treeData[event];
      if (item && item.children) {
          treeChildren.value = item.children;
          const firstChild = item.children[0];
          activeChildrenId.value = firstChild.id;
          activeChildrenIndex.value = firstChild.id;
      }
  }
</script>
