Thank you Pete!
Actually, my problem is that I created a custom contentpart, namely BookPart (it is associated with BookPartRecord).
I added a template under Views EditorTemplates Parts. It works good within the cms admin zone.
Now I would like my users to create book content within custom front pages. I added a membercontroller for this and this controller includes an action method, namely AddBook.
I created a view AddBook.cshtml and in that view I would like to display the form that I use in admin zone. To do that I use @Display but it comes with the default save button.
I hope I could describe what I want to do.
