The Defining Selections property governs the selections your site will use. The selections that display on your site contain products with a property value that matches the faceting property value associated with the selection. Use the Defining Selections property to decide how selections are created and consequently, what they will contain. There are four options for this property:
One Selection for Each Value creates one selection for each faceting property value. For a manufacturer facet, for example, each selection represents one manufacturer name.
Dynamic Selections uses the guidelines you specify to create selections dynamically. Typically, each selection represents several faceting property values. A price facet, for example, produces selections that represent a range of prices.
Guided Selection Ranges uses the exact requirements you provide to create selections dynamically. Typically, each selection represents several faceting property values. A Monitor size facet, for example, produces selections that represent a range of sizes. This option is available only if the faceting property is a number.
Specified Selections creates the selections you define. Each selection represents a range of faceting property values. A price facet, for example, creates selections, each of which represents the exact range of faceting property values you provided. This option is available only if the faceting property is a number.
Keep in mind that, when you use any value other than One Selection for Each Faceting Property Value, you specify parameters that determine the selections that display. If it is impossible to generate selections based on the parameters you specify, for example you use the Guided Selection Ranges and require 5 selections when only 4 are possible, ATG Merchandising won’t generate any selections.
With the Defining Selections property, you specify settings that determine selections on your site, which in turn determines the criteria for the products held by each selection. Note that the order of products in the selection is in no way affected by settings you provide here. For example, defining alphabetical selections ensures that each selection contains products in the appropriate letter range, but it doesn’t alphabetize the products in that selection.
