## searchApi

**发送**

默认 GET，携带 term 变量，值为搜索框输入的文字，可从上下文中取数据设置进去。

**响应**

格式要求如下：

```json
{
  "status": 0,
  "msg": "",
  "data": {
    "options": [
      {
        "label": "描述",
        "value": "值" // ,
        // "children": [] // 可以嵌套
      },

      {
        "label": "描述2",
        "value": "值2"
      }
    ],

    "value": "值" // 默认值，可以获取列表的同时设置默认值。
  }
}
```

适用于需选择的数据/信息源较多时，用户可直观的知道自己所选择的数据/信息的场景，一般左侧框为数据/信息源，右侧为已选数据/信息，被选中信息同时存在于 2 个框内。

## 属性表

除了支持 [普通表单项属性表](./formitem#%E5%B1%9E%E6%80%A7%E8%A1%A8) 中的配置以外，还支持下面一些配置
