表单项默认都是一行显示一个Group 组件用于在一行展示多个表单项
## 基本用法
```schema:height="360" scope="body"
{
"type": "form",
"controls": [
{
"type": "text",
"name": "text",
"label": "文本"
},
{
"type": "divider"
},
{
"type": "group",
"controls": [
{
"type": "text",
"name": "text1",
"label": "文本1"
},
{
"type": "text",
"name": "text2",
"label": "文本2"
}
]
}
]
}
```
## 展示
可以给`group`组件设置`mode`调整展示模式,用法同 [Form 展示](../form/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:height="360" scope="body"
{
"type": "form",
"controls": [
{
"type": "text",
"name": "text",
"label": "文本"
},
{
"type": "divider"
},
{
"type": "group",
"mode": "horizontal",
"controls": [
{
"type": "text",
"name": "text1",
"label": "文本1"
},
{
"type": "text",
"name": "text2",
"label": "文本2"
}
]
}
]
}
```
当表单在水平模式下时,如果`group`内表单项设置`"label": false`,会导致布局错乱,如下
```schema:height="360" scope="body"
{
"type": "form",
"mode": "horizontal",
"controls": [
{
"type": "text",
"name": "text",
"label": "文本"
},
{
"type": "divider"
},
{
"type": "group",
"controls": [
{
"type": "text",
"name": "text1",
"label": false
},
{
"type": "text",
"name": "text2",
"label": false
}
]
}
]
}
```
这时可以给`group`配置`label`属性,保持和其他表单项布局统一
```schema:height="360" scope="body"
{
"type": "form",
"mode": "horizontal",
"controls": [
{
"type": "text",
"name": "text",
"label": "文本"
},
{
"type": "divider"
},
{
"type": "group",
"label": "文本组",
"controls": [
{
"type": "text",
"name": "text1",
"label": false
},
{
"type": "text",
"name": "text2",
"label": false
}
]
}
]
}
```
