Product Catalog Category Type

[hakkani]

Hi, when I try to create a new Category as say "TESTCA", and then add some Categories which already have products into this category, but when I select the "TESTCA" category in the eCommerce, the screen showed "No PROMOTION Category".

But when I change one of the category's type to be "Promotions (One)" and then the products would show in the eCOMMERCE.

WHY?

Could somebody help to explain what "Product Catalog Category Type" is?

Are these "Product Catalog Category Type" predefined by ofbiz, could we add or change them? how?
