In the "Template" tab you can set which fields will be visible in the application and in what order. You have two options:
- use the already available fields and customize them to suit your needs,
- create new ones using the "Add additional field" button.
When adding a new field, you need to choose the name of it and pick the type from the list.
You also need to set if the field is going to be hidden, required, unique or read-only.
