I need to create list in SharePoint 2010 with the following requirements. When anybody will try to create new item it will have some kind of header and body. In header it will input for example name and in body will have 2 items(car and color). Also user need to have option add new car and automatically another body should start(car and color)(it is more less like the option in Infopaths form where user are adding new item). Do you have an idea how can I start this task?
