The Project History of Action Items is a list of all action items submitted on a particular project. This module can be accessed by opening the specific project, then clicking the “Action Items” button under the history heading on the left-hand hamburger menu. You can see open, completed, and rejected action items here. This grid is also filterable (more information on filtering grids here), and can be arranged in a layout that better suits your needs (more information on grid layouts here).

You can double click on an action item to view the details in the regular action item window rather than list form.
