The Task Checklist is available under the Custom - Managed section of the page designer's component palette. There are two options available for this component:
-
Header Title: optionally display a title above the Task Checklist.
- Enable Time Column: when enabled, displays the Task's Logged Time. This option would not be enabled for organizations not tracking time.
