Create a block within a category and by default load a list Object


Hello good everyone.
I present my case.

I have a .net 4.6.1 project with cms and commerce

I need to create a block within a category and load a list by default, to speed up the work of the editors.

for this, I have created a block that contains

public virtual IList<FlagsOrderModel>


public class FlagsOrderModel

        [Display(Name = @"Name", Order = 10)]
        public virtual string Name { get; set; }

        [Display(Name = @"Url", Order = 10)]
        public virtual Url Url{ get; set; }


my problem is that i can't load this blocke with predefined data.

[Display(Name = @"Brand List", Order = 10)]
[EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor<FlagsOrderModel>))]
public virtual IList<FlagsOrderModel> Flags{ get; set; }

1st to be able to load the block with predefined flags
and second I would try to make this list automatic
making a select of the category in which this block is created and obtain a list of product brands.

can someone give me an idea?

I have tried with


[EditorDescriptorRegistration(TargetType = typeof(string), UIHint = "ListStringMarks")]
    public class SituationMultipleEditorDescriptor : EditorDescriptor
        public override void ModifyMetadata(ExtendedMetadata metadata, IEnumerable<Attribute> attributes)
            SelectionFactoryType = typeof(SituationMarcasFactory);
            ClientEditingClass = "epi-cms/contentediting/editors/SelectionEditor";

            base.ModifyMetadata(metadata, attributes);
    public class SituationMarcasFactory : ISelectionFactory
        public IEnumerable<ISelectItem> GetSelections(ExtendedMetadata metadata)
            var situation = new List<SelectItem>();
            situation.Add(new SelectItem() { Value = "Adidas", Text = "Adidas" });
            situation.Add(new SelectItem() { Value = "Nike", Text = "Nike" });

            return situation;

Without any result.

The targe type of your editor descriptor does not match your property type.

this has been a mistake

even with this correct. I can't get the list to load the predefined data by default.


[EditorDescriptorRegistration(TargetType = typeof(string), UIHint = "ListStringFlags")]

I don't really understand exactly what you are trying to do.

A couple examples.

A dropdown list property:

Property list / collections editor:

And them combining them:
