`notification` also provides a global `config()` method that can be used for specifying the default options. Once this method is used, all the notification boxes will take into account these globally defined options when displaying.
2016-08-17 11:07:02 +08:00
- `notification.config(options)`

## FAQ
2020-02-07 20:32:00 +08:00
### Why I can not access context, redux in notification?

antd will dynamic create React instance by `ReactDOM.render` when call notification methods. Whose context is different with origin code located context.
2020-02-07 17:55:27 +08:00
When you need context info (like ConfigProvider context), you can use `notification.useNotification` to get `api` instance and `contextHolder` node. And put it in your children:
```tsx
const [api, contextHolder] = notification.useNotification();
return (
< Context1.Provider value = "Ant" >
2020-03-30 16:17:12 +08:00
{/* contextHolder is inside Context1 which means api will get value of Context1 */}
2020-02-07 17:55:27 +08:00
{contextHolder}
< Context2.Provider value = "Design" >
2020-03-30 16:17:12 +08:00
{/* contextHolder is outside Context2 which means api will **not** get value of Context2 */}
2020-02-07 17:55:27 +08:00
< / Context2.Provider >
< / Context1.Provider >
);
```
**Note:** You must insert `contextHolder` into your children with hooks. You can use origin method if you do not need context connection.
