Hello Tuan, is it possible to update Themes - Registrants Management with a Show Past Events - Show or Hide option?
This would enable admins to have a view of the next events Registrants without having do any searches etc and they could they create a seperate menu for past Registrants if needed
I just have it implemented. You can access to My Downloads menu item, download latest package, upgrade it to your site
Then edit the menu item, there is a parameter called Show Registrants Of Past Events. By default, it set to Yes. You can change it to No and it should work as you want
