What does it mean to "hide' an Activity? It means that the Activity is no longer viewable to Account Holders and/or Instructors (depending on your settings).
Enrollsy has always allowed you to hide default Activities (except the Check In and Check Out Activities), which are:
Health Check
Photo
Note
Absent
Present
Here's how to hide custom Activities:
Go to the Activities page
Turn off the blue switch beside whichever Activity (default or custom) that you want to hide:
Unhide Activities
You can view all hidden Activities by clicking the "Show Hidden" button at the top of the Activities list.
To unhide an Activity, click the "Show Hidden" button and then switch the toggle to the "on" position to show the Activity again.
