It is possible to have application pages in two different languages connected to the same event. When creating an event you can choose if you want to add an additional application page in a different language. Navigate to the tab “Settings” and choose and additional language in the dropdown “Alternate language”
You will now get two sets of information text fields, one for each application page. Global settings for the event such as maximum amount of participants or if the applications should be auto-confirmed are not duplicated.
You also have language specific confirmation e-mails depending on which language the application was submitted from. Applications from an English application page will get English confirmation e-mails, and application from a Swedish application page will get Swedish confirmation e-mails
