# GrapesJs Notifications Plugin

Centralized notification system for GrapesJS plugins. Displays errors, warnings and activity messages in a consistent UI.

It displays various types of notifications including errors, warnings, and activities, thereby facilitating a more interactive and responsive interface. The most important feature is probably that it allows users to interact with the notifications by clicking on them to select a specific component in the editor, go to a page or scroll to the component.

The notifications are styled using the following CSS classes:

* `.gjs-notification` - The notification container

* `.gjs-notification__item` - The notification item
* `.gjs-notification__error` - The error notification
* `.gjs-notification__warning` - The warning notification
* `.gjs-notification__success` - The success notification
* `.gjs-notification__info` - The info notification
* `.gjs-notification__message` - The notification message
* `.gjs-notification__close` - The close button for the notification

```css
.gjs-notification {
  padding: 10px;
  margin: 10px;
  border-radius: 5px;
  box-shadow: 0 0 5px rgba(0,0,0,.3);
}
```
