PropertyGrid & Object Property: Category

I'm working on a project that involves viewing and changing the properties of a class element with the PropertyGrid control. The properties of the class element are references to other objects (themselves) have properties.

[TypeConverter(typeof(ExpandableObjectConverter))]
public abstract class Elemento
{  
   ....

   [CategoryAttribute("Materiale Associato 1"), DescriptionAttribute("Caratteristiche standard del Materiale 1")]
   public Standard1 Standard1 {get;set;}

   [CategoryAttribute("Materiale Associato 2"), DescriptionAttribute("Caratteristiche standard del Materiale 2")]
   public Standard2 Standard2 {get;set;}
}

This object will passed to the SelectedObject property (PropertyGrid). I would like to divide the properties of the class Standard1 (and Standard2) into categories. I tried to decorate the properties in this way:

[TypeConverter(typeof(Standard1Converter))]
public class Standard1
{  
   [CategoryAttribute("Property1")]
   public AnObject Property {get;set;}

   [CategoryAttribute("Property2"), DescriptionAttribute("A property")]
   public AnObject Property2 {get;set;}

but the properties are not grouped. I see only the description. What is wrong?

NB: Standard1Converter : ExpandableObjectConverter

There is no subcategories in the standard MS PropertyGrid. This means that only the top level object passed to SelectedObject will be categorized.
