All nice notifications can be managed from their own list. Create, delete, re-order, even translate if using WPML. Everything you can do with to manage your notifications, is done from this list.
Sometimes when you use more than one notification on the same page, you will want to order them as you will. Just drag and drop the notifications on the list to reorder them.
Each notification has a set of global options that will affect the style and behavior of the notification container. You can set these options from the edit alert page. You can farther style your notification by adding custom CSS code to it.
Right below the global options, you will find the Visual Composer. Create new layers, position them using your mouse, and start styling them. You can also set inline CSS code to them. Posibilities are endless.
If you set your notification to be shown only on certain pages, you will have to go to that page editor and select what notification you want to show in it. As easy as that.
