What is the difference between Project and Section fields and Project and Section relations?

The regular Project and Section Name fields allow you to enter text or select an option from a dropdown manually but don't create dynamic links to other pages.

In contrast, the Project Relation and Section Relation fields are used to create linked relations between pages.

Specifically:

• The Project Relation field allows you to link a page to another database page that represents a project. This enables you to associate items with projects.
• The Section Relation field allows you to link a page to another database page that represents a section or category. This enables you to categorize items into different sections.

You can add these by clicking on + Add Field below the listed fields.

These relation fields require that the related pages are also stored as databases in Notion and connected to 2sync. The relation field then links to a specific page in the associated database.
