## 基本使用

```schema:height="400" scope="body"
{
    "type": "form",
    "api": "https://houtai.baidu.com/api/mock2/form/saveForm",
    "controls": [
        {
            "name": "text",
            "type": "text",
            "label": "text"
        }
    ]
}
```

## 不同类型

配置`type`可以支持不同格式的文本输入框

```schema:height="550" scope="body"
{
    "type": "form",
    "api": "https://houtai.baidu.com/api/mock2/form/saveForm",
    "controls": [
        {
            "name": "text",
            "type": "text",
            "label": "text"
        },
        {
            "type": "divider"
        },
        {
            "type": "url",
            "name": "url",
            "label": "链接"
        },
        {
            "type": "divider"
        },
        {
            "type": "email",
            "name": "email",
            "label": "邮箱"
        },
        {
            "type": "divider"
        },
        {
            "type": "password",
            "name": "password",
            "label": "密码"
        }
    ]
}
```

## 附加组件

可以配置`addOn`，附带附加组件

```schema:height="400" scope="body"
{
    "type": "form",
    "api": "https://houtai.baidu.com/api/mock2/form/saveForm",
    "controls": [
        {
            "name": "text",
            "type": "text",
            "label": "text",
            "addOn": {
                "type": "button",
                "label": "搜索"
            }
        }
    ]
}
```

## 选择器模式

配置`options`即可支持选择器模式。

```schema:height="400" scope="body"
{
    "type": "form",
    "api": "https://houtai.baidu.com/api/mock2/form/saveForm",
    "controls": [
        {
            "name": "text",
            "type": "text",
            "label": "text",
            "options": [
                {
                    "label": "OptionA",
                    "value": "a"
                },
                {
                    "label": "OptionB",
                    "value": "b"
                },
                {
                    "label": "OptionC",
                    "value": "c"
                },
                {
                    "label": "OptionD",
                    "value": "d"
                }
            ]

        }
    ]
}
```

选择器模式下，支持部分选择器组件支持的配置项，具体请查看下面的属性表
