How can I add a subpanel to a module?
Sorry, i dont see for which version of sugar you need to do that. For 7.x you can go to studio and the module you want it to have the subpanel, then create a new relationship of one-to-many with the module you want as subpanel.
hope it helps
Simply Add one to many relationship between the modules in which you want Subpanel through studio then it will auto populate the subpanels.
