Boards can be used for a variety of construction projects and home improvements. Smaller sized boards can be used as casing, shelf cleats or front edges, cabinet door stiles and rails, bases, wall and cabinet panels, pilasters and more. Larger sized boards can be used for a variety of uses such as stair stringers, door jambs, columns, stair posts, ceiling beams, shelves, and to create coffered ceilings.
All board products list the dimensions as common size first, followed by the actual size in parenthesis
You do not have a link list with a handle set to board, or you do and it's empty.
Go ahead and create a link list called Board on your Navigation page and populate that link list with links that point to collections, to see collections listed here.
Make sure the link list also has a handle set to board.
