Comments and Uploads must first be enabled by an admin, and a new checklist template will need to be created in order to utilize this functionality.
Checklists created from a template with the setting "Comments & file upload" turned ON support comments & file upload, people with access to the checklist can now expand any task and add a comment or upload a file to it.
When people type a comment and click post, the comment is now added to the task and the date and time of creation is displayed under it.
Placing the mouse over the comment will show the edit and delete options. When an edit is made to the posted comment the displayed date and time of the comment will be updated to reflect the date and time of the edit.
To add a file, the process is similar to adding text. People will click attach file, select the file from their desktop and the file upload process will begin.
Once the file is uploaded, the poster can remove it or post it to the task.
When a file is posted, anyone with access to this checklist can download it.
To remove a comment, the creator places the mouse cursor over their comment and clicks the delete button. A confirmation modal is then shown to confirm the action and the comment is removed.
The mobile experience is very similar, the primary difference is that comment action icons are visible at all time.
