用于实现多选。

## 基本用法

```schema: scope="body"
{
    "type": "form",
    "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
    "controls": [
        {
        "name": "checkboxes",
        "type": "checkboxes",
        "label": "复选框",
        "options": [
            {
                "label": "OptionA",
                "value": "a"
            },
            {
                "label": "OptionB",
                "value": "b"
            },
            {
                "label": "OptionC",
                "value": "c"
            },
            {
                "label": "OptionD",
                "value": "d"
            }
            ]
        }
    ]
}
```

## 展示多行

可以配置`columnsCount`属性调整展示列的个数

```schema: scope="body"
{
    "type": "form",
    "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
    "controls": [
        {
            "name": "checkboxes1",
            "type": "checkboxes",
            "label": "默认的复选框",
            "options": [
                {
                    "label": "OptionA",
                    "value": "a"
                },
                {
                    "label": "OptionB",
                    "value": "b"
                },
                {
                    "label": "OptionC",
                    "value": "c"
                },
                {
                    "label": "OptionD",
                    "value": "d"
                }
            ]
        },
        {
            "type": "divider"
        },
        {
            "name": "checkboxes2",
            "type": "checkboxes",
            "label": "显示两列的复选框",
            "columnsCount": 2,
            "options": [
                {
                    "label": "OptionA",
                    "value": "a"
                },
                {
                    "label": "OptionB",
                    "value": "b"
                },
                {
                    "label": "OptionC",
                    "value": "c"
                },
                {
                    "label": "OptionD",
                    "value": "d"
                }
            ]
        }
    ]
}
```

## 属性表

当做选择器表单项使用时，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
