卡片展示，不支持配置初始化接口初始化数据域，所以需要搭配类似像`Service`这样的，具有配置接口初始化数据域功能的组件，或者手动进行数据域初始化，然后通过`source`属性，获取数据链中的数据，完成数据展示。
## 基本用法
这里我们使用手动初始数据域的方式，即配置`data`属性，进行数据域的初始化。
```schema
{
"type": "page",
"data": {
"items": [
{
"engine": "Trident",
"browser": "Internet Explorer 4.0",
"platform": "Win 95+",
"version": "4",
"grade": "X"
},
{
"engine": "Trident",
"browser": "Internet Explorer 5.0",
"platform": "Win 95+",
"version": "5",
"grade": "C"
},
{
"engine": "Trident",
"browser": "Internet Explorer 5.5",
"platform": "Win 95+",
"version": "5.5",
"grade": "A"
},
{
"engine": "Trident",
"browser": "Internet Explorer 6",
"platform": "Win 98+",
"version": "6",
"grade": "A"
},
{
"engine": "Trident",
"browser": "Internet Explorer 7",
"platform": "Win XP SP2+",
"version": "7",
"grade": "A"
}
]
},
"body": {
"type": "cards",
"source": "$items",
"card": {
"body": [
{
"label": "Engine",
"name": "engine"
},
{
"label": "Browser",
"name": "browser"
},
{
"name": "version",
"label": "Version"
}
],
"actions": [
{
"type": "button",
"level": "link",
"icon": "fa fa-eye",
"actionType": "dialog",
"dialog": {
"title": "查看详情",
"body": {
"type": "form",
"body": [
{
"label": "Engine",
"name": "engine",
"type": "static"
},
{
"name": "browser",
"label": "Browser",
"type": "static"
},
{
"name": "version",
"label": "Version",
"type": "static"
}
]
}
}
}
]
}
}
}
```
或者你也可以使用 CRUD 的 [card 模式](./crud#cards-%E5%8D%A1%E7%89%87%E6%A8%A1%E5%BC%8F)
## 当 cards 在 crud 中且配置了批量操作按钮时可点选
如果配置了 `checkOnItemClick`，当用户点击卡片时就能选中这个卡片，而不是只能点击勾选框才能选中

> 6.4.0 或更高版本
当前组件对外暴露以下特性动作，其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作，动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数，详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。

`args.condition` 可选，通过表达式指定更新哪些行，支持条件组合 index` | 设置列表的选中项 |
| selectAll | - | 设置列表全部项选中 |
| clearAll | - | 清空列表所有选中项 |

```
#### 更新指定行记录
可以通过指定`index`或者`condition`来分别更新指定索引的行记录和指定满足条件（条件表达式或者 ConditionBuilder）的行记录，另外`replace`同样生效，即可以完全替换指定行记录，也可以对指定行记录做合并。

"type": "page",
