OroCatalogBundle defines the master catalog and the categories that are aimed at structuring products in OroCommerce.
The bundle provides the ability to manage categories and assign products to them.
Default Product Options
The Default Product Options section is displayed on the create or edit pages of a particular master catalog category. The section contains the Unit of Quantity field that is shown by default in the product details page in the storefront, and the Precision field for the quantity that a user may order or add into the shopping list.
If both the unit of quantity and precision are specified, then all new products in this category will have these values preselected during creation.
The section provides notes about improving performance of catalogs in large datasets.
