Hi Anibal,
"canbelisted" defines who is shown in the list when you are taking attendance. By default it is given to the student role. Users that do not have this capability will not appear in the list.
hopefully that makes sense?
Thanks for your answer. But the issue is that if " Capabilities / mod / attendance: canbelisted" is not enabed, nobody sees the assistance, it does not work
I have obvious "enable".
Don't worry... It was a curiosity!
