Because the Root category is the highest level of category, it cannot be deleted while it is active or has a store associated with it. As a result, if you want to delete a root category, you must first determine its status.
In Magento 2, the root categories serve as a container for the main menu. When you have many stores and want to display different categories as a root category in each store, you can use this method. You can do so using Magento 2!
