Each node category that you have created using the Source Category Class and/or Target Category Class fields will have a separate Node Category section. For example, if you have created three node categories, you’ll see three sections – Node Category 1, Node Category 2, and Node Category 3.

Each of these sections contain various properties that can be used to apply category-specific customization settings to all nodes assigned to the category. These settings will take priority over Nodes (Default Category) settings, allowing you to visually distinguish each category.
