To create categories, please follow the instructions as below:
Step 1: Firstly, go to Components > TZ Portfolio Plus> Categories and click New button.
Step 2: After that, please type Tittle (required) and other information.
Step 3: Finally, save the category.
NOTE: In the TZ Portfolio Plus, there is one feature which is useful to users.
It is "Inherit parameter options from category".
It means that: "Setting this option will make this category inherit all parameters from another category, thus you don't have to re-set all options in this one if they are the same with another category's. This setting is very useful when you are creating child categories which share the same parameters with their parent category. You can use this feature and then you only configure in some categories. you do not have to configure in all categories."
