## 基本用法

```schema: scope="body"
{
  "type": "breadcrumb",
  "items": [
    {
      "label": "首页",
      "href": "https://baidu.gitee.com/",
      "icon": "fa fa-home"
    },

    {
      "label": "上级页面"
    },

    {
      "label": "<b>当前页面</b>"
    }
  ]
}
```

## 动态数据

可以配置 source 来获取上下文中的动态数据，结合 [service](service) 来实现动态生成。

```schema
{
  "type": "page",
  "data": {
    "breadcrumb": [
      {
        "label": "首页",
        "href": "https://baidu.gitee.com/"
      },

      {
        "label": "上级页面"
      },

      {
        "label": "<b>当前页面</b>"
      }
    ]
  },
  "body": {
    "type": "breadcrumb",
    "source": "${breadcrumb}"
  }
}
```

## 分隔符

```schema: scope="body"
{
  "type": "breadcrumb",
  "separator": ">",
  "separatorClassName": "text-black",
  "items": [
    {
      "label": "首页",
      "href": "https://baidu.gitee.com/",
      "icon": "fa fa-home"
    },

    {
      "label": "上级页面"
    },

    {
      "label": "<b>当前页面</b>"
    }
  ]
}
```
