The store.war/cartridges/ProductListCategoryChildren/ProductListCategoryChildren.jsp page renders the content in the ProductListCategoryChildrenContentItem object. This renderer retrieves the categoryId value from the ProductListCategoryChildrenContentItem object and uses this value as a parameter to the /atg/commerce/catalog/CategoryLookup servlet bean to retrieve the category and its child products from the Catalog repository. The child products are then passed to the /atg/store/sort/RangeSortDroplet servlet bean, along with the recordsPerPage value returned in the content item, to sort and render the child product list.
