To achieve 0..1 you need to have a special item "Nothing" with value '' (empty string) and in order to add this item to a Page (actually DatabaseList) property you have to write a custom displayer. Another solution may be to create a special page with a MyClass object that represents the "nothing" value (when selected), but you still need to hack something in order to have this option displayed first. > > Do you have an idea, how can I do that? > > I found a issue too: my select list list all page (with MyClass object) ... > even my Template with MyClass object who is hidden. Does it behave the same with a DatabaseList property? The Page property is nothing more than a wrapper for the DatabaseList property.
