Portlets are small expandable windows representing a specific theme or particular subject matter. They are only available on dashboards and they display data based on association, ownership, or applied filters. Portlets provide a concise way to organize, present, and assess project data within a single page and also offer tools for adding, modifying, and personalizing portfolio, project, and resource data. Portlets on shared dashboards provide a centralized place for collaborating with other users.
