The ExPropertiesList control is able to categorize object properties. Use the ShowCategories property to enable categories into your control. Use the Category property to check if an item is a property or it is a category. 

The following sample shows how to include only the properties in the "Misc" category:

Private Sub PropertiesList1_IncludeProperty(ByVal Property As EXPROPERTIESLISTLibCtl.IProperty, Cancel As Boolean)
    Cancel = Not (Property.CategoryName = "Misc")
End Sub
