You can display quote line items in a single template section that references a template content record with a Type of "Line Items". Alternatively, you could display line items in several different template sections.
You can list all your hardware products in one section while the software licenses for those hardware products are listed in a separate section. You can even have a separate introductory/descriptive text for each section.
The picture below illustrates how your generated quote document could appear with separate sections of filtered line items and introductory text for each. The intro sections are highlighted with a blue arrow, while the filtered line items sections are boxed in green.
Before you begin, determine which fields you want to use to filter these lists of product line items. In the example above, you may want to use the Product Family field on the Products object to filter hardware from shipping products. Whatever fields you intend to use in your filter, add the API name of that field as a value in the Filter Field picklist on the Template Section object.
SteelBrick CPQ also allows you to customize which line item sections contain subtotals. For example, you might want to hide totals in your section of Shipping Line Items, yet display totals in your Hardware Line Items list.
