Out of the box you will have an example of category management (for the cases in which you are developing a blog or a shop). To access this example, click the `Examples (API)/Category Management` link in the left sidebar or add /examples/category-management/list-categories to the URL. You can add and edit categories here, but you can only delete them if they are not attached to any items.
You can find the compoments for category functionality in `src\views\examplesApi\CategoryManagement` folder. The store used for category functionality is found in `src\store\category.module.js` and you can find the service file in `src\services\category.service.js`.
