FieldSet 是用于分组展示表单项的一种容器型组件，可以折叠。

## 基本用法

可以通过配置标题`title`和表单项数组`controls`，实现多个表单项分组展示

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "controls": [
    {
      "type": "fieldSet",
      "title": "基本配置",
      "controls": [
        {
          "name": "text1",
          "type": "text",
          "label": "文本1"
        },

        {
          "name": "text2",
          "type": "text",
          "label": "文本2"
        }
      ]
    }
  ]
}
```

## 展示模式

可以通过设置`mode`调整展示模式，用法同 [Form 展示模式](./index#%E8%A1%A8%E5%8D%95%E5%B1%95%E7%A4%BA)

下面`group`我们配置了`"mode": "horizontal"`，观察显示情况

```schema: scope="body"
{
  "type": "form",
  "controls": [
    {
        "type": "text",
        "name": "text",
        "label": "文本"
    },
    {
        "type": "divider"
    },
    {
      "type": "fieldSet",
      "title": "基本配置",
      "mode": "horizontal",
      "controls": [
        {
          "name": "text1",
          "type": "text",
          "label": "文本1"
        },

        {
          "name": "text2",
          "type": "text",
          "label": "文本2"
        }
      ]
    }
  ]
}
```

## 可折叠

配置`"collapsable": true`可以实现点击标题折叠显隐表单项。

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "controls": [
    {
      "type": "fieldSet",
      "title": "基本配置",
      "collapsable": true,
      "controls": [
        {
          "name": "text1",
          "type": "text",
          "label": "文本1"
        },

        {
          "name": "text2",
          "type": "text",
          "label": "文本2"
        }
      ]
    }
  ]
}
```

### 默认是否折叠

默认是展开的，如果想默认折叠，那么配置`"collapsed": true`默认折叠。

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "controls": [
    {
      "type": "fieldSet",
      "title": "基本配置",
      "collapsable": true,
      "collapsed": true,
      "controls": [
        {
          "name": "text1",
          "type": "text",
          "label": "文本1"
        },

        {
          "name": "text2",
          "type": "text",
          "label": "文本2"
        }
      ]
    }
  ]
}
```

## 标题放底部

fieldSet 的另一种标题展现样式，不同的是展开的时候收起文本是在下方的，如果组件比较多的时候更容易收起。

设置 `"titlePosition": "bottom"`。

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "controls": [
    {
      "type": "fieldSet",
      "title": "展开更多设置",
      "collapseTitle": "收起设置",
      "titlePosition": "bottom",
      "collapsable": true,
      "collapsed": true,
      "controls": [
        {
          "name": "text1",
          "type": "text",
          "label": "文本1"
        },

        {
          "name": "text2",
          "type": "text",
          "label": "文本2"
        }
      ]
    }
  ]
}
```
