Question

Hello,
I have a number of databases, each with projects, viewed in Board View.
Each project has a number of sub-items, (tasks to complete).
I have the completed checkbox selected once a sub-item is completed.
I don't see ability to set a filter on the board, (or page view of the board) that allows me to only show uncompleted, (unchecked) sub-items.
While I can view or hide completed boards in the Database view, I was hoping to have boards represent main projects and sub-items represent individual tasks to complete.
Thank you,
