Filter on Category  

Select one or more items from this field to restrict filtered items to items associated with the selected categories.

You can use categories to group and subdivide items such as tasks and faqs. You can sort by category, or use categories in filters.

You can use categories to index your data. You can cross-link by allowing categories to span both tasks and faqs. You can organize further by using task- or faq-specific categories.

The category field is optional, so if you select all categories, items having no categories will be filtered out.
