```schema: scope="body"
{
    "type": "button-toolbar",
    "className": "block m-t",
    "buttons": [
        {
            "type": "button",
            "label": "自定义宽度",
            "actionType": "drawer",
            "drawer": {
                "position": "right",
                "width": 300,
                "title": "提示",
                "body": "这是个自定义300px宽度的弹框"
            }
        },
        {
            "type": "button",
            "label": "自定义高度",
            "actionType": "drawer",
            "drawer": {
                "position": "bottom",
                "height": 300,
                "title": "提示",
                "body": "这是个自定义300px高度的弹框"
            }
        },
    ]
}
```
