You can choose to set up different types of input fields depending on your content. For instance, a blog might have a title, a slug, and a long-form field for formatted content. These may be different for a product directory or a photo blog, where you may need to add an image field. To edit the fields each CMS item will have, click on any of the column titles. This will trigger a modal to add new fields, where you can also re-arrange the fields or modify or delete the existing ones
