You can configure which standard columns and actions are available in the catalog, attribute, bundle, and shopping cart pages, the style they use, and the order in which they are displayed. Additionally, you can create your own custom fields and actions and display them in these Visualforce pages.
The Visualforce pages are used for product selection, select attributes, options, and in the cart page change quantities, apply discounts, and more for your quote/proposal. If there are default fields and actions that are not required, or new fields you want to add, you can make those changes through the CPQ Config Settings tab.
Configuring Display Column Settings The Display Column Settings enable you to display only those key fields needed to quickly and easily configure your quote/proposal.
Configuring Display Action Settings The Display Action Settings page provides a simple interface for selecting actions, applying styles, and reordering them. You can even create and use your own custom action.
