Vxe UI vue vxe-form 实现折叠表单，当表单很多时实现自动收起与展开

代码

folding 用于将当前表单项设置为默认隐藏
collapse-node 设置折叠按钮，加上之后会自动在该表单项的右侧显示一个折叠按钮

<template>
  <div>
    <vxe-form
      title-colon
      ref="formRef"
      title-width="100"
      title-align="right"
      :data="formData"
      @submit="submitEvent">
      <vxe-form-item title="名称" field="name" span="12">
        <template #default="params">
          <vxe-input v-model="formData.name"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="昵称" field="nickname" span="12">
        <template #default="params">
          <vxe-input v-model="formData.nickname"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="角色" field="role" span="12" folding>
        <template #default="params">
          <vxe-input v-model="formData.role"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="性别" field="sex" span="12" folding>
        <template #default="params">
          <vxe-input v-model="formData.sex"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="年龄" field="age" span="12" folding>
        <template #default="params">
          <vxe-input v-model="formData.age"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="大小" field="num" span="12" folding>
        <template #default="params">
          <vxe-input v-model="formData.num"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="创建时间" field="createDate" span="12" folding>
        <template #default="params">
          <vxe-input v-model="formData.createDate"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item title="更新时间" field="updateDate" span="12" folding>
        <template #default="params">
          <vxe-input v-model="formData.updateDate"></vxe-input>
        </template>
      </vxe-form-item>
      <vxe-form-item align="center" span="24" collapse-node>
        <template #default>
          <vxe-button type="submit" status="primary" content="搜索"></vxe-button>
        </template>
      </vxe-form-item>
    </vxe-form>
  </div>
</template>

<script setup>
import { ref } from 'vue'
import { VxeUI } from 'vxe-pc-ui'

const formRef = ref()
const formData = ref({
  name: 'test1',
  role: '',
  nickname: 'Testing',
  sex: '',
  age: '',
  num: '',
  createDate: '',
  updateDate: ''
})

const changeEvent = (params) => {
  const $form = formRef.value
  if ($form) {
    $form.updateStatus(params)
  }
}

const submitEvent = () => {
  VxeUI.modal.message({ content: '保存成功', status: 'success' })
}
</script>

效果如下：

配置式表单也是一样的

<template>
  <div>
    <vxe-form v-bind="formOptions" v-on="formEvents" ></vxe-form>
  </div>
</template>

<script setup>
import { reactive } from 'vue'
import { VxeUI } from 'vxe-pc-ui'

const formOptions = reactive({
  titleWidth: 100,
  titleColon: true,
  titleAlign: 'right',
  data: {
    name: 'test1',
    role: '',
    nickname: 'Testing',
    sex: '',
    age: '',
    num: '',
    createDate: '',
    updateDate: ''
  },
  items: [
    { field: 'name', title: '名称', span: 12, itemRender: { name: 'VxeInput' } },
    { field: 'nickname', title: '昵称', span: 12, itemRender: { name: 'VxeInput' } },
    { field: 'role', title: '角色', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'sex', title: '性别', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'age', title: '年龄', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'num', title: '大小', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'createDate', title: '创建时间', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'updateDate', title: '更新时间', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    {
      align: 'center',
      span: 24,
      collapseNode: true,
      itemRender: {
        name: 'VxeButtonGroup',
        options: [
          { type: 'submit', content: '搜索', status: 'primary' }
        ]
      }
    }
  ]
})

const formEvents = {
  submit () {
    VxeUI.modal.message({ content: '点击搜索', status: 'success' })
  }
}
</script>

也可以使用插槽

<template>
  <div>
    <vxe-form v-bind="formOptions" >
		<template #active>
			<vxe-button status="primary" @click="searchEvent">搜索</vxe-button>
		</template>
    </vxe-form>
  </div>
</template>

<script setup>
import { reactive } from 'vue'
import { VxeUI } from 'vxe-pc-ui'

const formOptions = reactive({
  titleWidth: 100,
  titleColon: true,
  titleAlign: 'right',
  data: {
    name: 'test1',
    role: '',
    nickname: 'Testing',
    sex: '',
    age: '',
    num: '',
    createDate: '',
    updateDate: ''
  },
  items: [
    { field: 'name', title: '名称', span: 12, itemRender: { name: 'VxeInput' } },
    { field: 'nickname', title: '昵称', span: 12, itemRender: { name: 'VxeInput' } },
    { field: 'role', title: '角色', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'sex', title: '性别', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'age', title: '年龄', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'num', title: '大小', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'createDate', title: '创建时间', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { field: 'updateDate', title: '更新时间', span: 12, folding: true, itemRender: { name: 'VxeInput' } },
    { align: 'center', span: 24, collapseNode: true, slots: { default: 'active' } }
  ]
})

const searchEvent = () => {
  VxeUI.modal.message({ content: '搜索', status: 'success' })
}
