To make curriculum tags available as loggable you must flag them as such in Manage Curriculum. If a tag is not set as loggable you will be able to assign it to a course, but it will not be visible under the Logging tab.
As of ME 1.13, you must build a curriculum tag set with at least 2 levels of hierarchy to make the tags available to leaners in their view. We are exploring options to eliminate this requirement but for ME 1.13 you must have a hierarchy and all levels of the hierarchy must be set to loggable.
You must be a user with administrative role permissions to edit curriculum tags.
Navigate to Admin>Manage Curriculum.
Click 'Curriculum Tags' from the Manage Curriculum card on the left sidebar.
Click on the appropriate curriculum tag set.
In list view, hover over a curriculum tag and click the pencil icon to edit the tag. In table view, click the pencil icon to edit the tag.
Click the checkbox beside "This curriculum tag should be loggable in the Experience Logbook."
Click 'Save'.
Tags set as loggable will be available to any course to which they are assigned.
