What kind of attribute is name?

The dropdown widget itself can only be used when the attribute is type: ENUM.

It really depends on what you want to do with this attribute (change its value, filter through a list of objects using the attribute Name or open all associations of your object, while using the name attribute for displaying each one individually).
