I have the following SharePoint list in which the "Participant" columns are text values (names of people) and each item in this list is a training event. "Evenement" is the type of training and "Jour" means day of the training.
What I need to do is whenever someone hovers on the name of a participant - I need their past training events to show. For example if "Participant 1" is Alpha and his "Jour 1" is on 11-05-2021 then "Jour 2" is on 12-05-2021 and "Jour 3" is 13-05-2021 and finally "Jour 4" is 14-05-2021. I need all this information to show on a hovercard if possible?
I am not sure if this makes complete sense or not and if it's even possible but any guidance would be appreciated, thank you in advance to anyone who replies and please be advised I'm only starting with JSON .
