Defining Facet Categories
Facet categories contain settings of categories that will be used for Pivot View. By defining face categories, you define possible ways of sorting collection items.
Click “Add new” in the “Facet Categories settings” block.
Enter name of facet category. Select type (the type field can be Number, String, LongString, DateTime, or Link.) Click “Save” to save the settings.
This way you can facet categories and use them for sorting in your Pivot View. Use arrows on the right to define order of facet categories.
When you have adjusted facet categories, move to the “Data source setting” section in order to map facet categories with existing list fields.
