EditorFor collection

Good day.

I have several objects, a table of techniques, with a Child-Parent connection inside the table (refers to itself)

public class Technic { //Это Идишник public Guid Id {get;set;} public string Name {get;set;} public int? Count { get; set; } public DateTime? ArrivalTime { get; set; } //тут указана ссылка на запись внутри таблицы техники public Guid? ParentId {get;set;} //Если запись Parent установлено на true public bool IsParent {get;set;} } 

and let the main model be Parking

 public class Parking { public Guid Id {get;set;} public string Name {get;set;} [UIHint("Technic")] public List<Technic> ParkingTechnic{get;set;} } 

so i have a controller

 public ActionResult ParkingAdd(){ var model = new Parking(){Id=Guid.NewGuid(), Name="Тест"}; //добавим категории model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Категория1", IsParent = true}); model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Категория2", IsParent = true}); //добавим технику model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Техника1", IsParent = false, ParentId=model.ParkingTechnic.First(l=>l.Name == ""Категория1"").Id}); model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Техника2", IsParent = false, ParentId=model.ParkingTechnic.First(l=>l.Name == ""Категория1"").Id}); model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Техника3", IsParent = false, ParentId=model.ParkingTechnic.First(l=>l.Name == ""Категория1"").Id}); //Добавим технику к второй категории model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Техника4", IsParent = false, ParentId=model.ParkingTechnic.First(l=>l.Name == ""Категория2"").Id}); model.ParkingTechnic.Add(new Technic(){Id = Guid.NewGuid(), Name = "Техника5", IsParent = false, ParentId=model.ParkingTechnic.First(l=>l.Name == ""Категория2"").Id}); return View(model) } 

Here is a view

 @Html.HiddenFor(m=>m.Id) @Html.TextBoxFor(m=>m.Name) //Отправим список в шаблон @Html.EditorFor(m=>m.ParkingTechnic) 

But the pattern

 @model List<Technic> @{ for (int i = 0; i> model.count(); i++){ @Html.LabelFor(m => m[i].Name) @Html.TextBoxFor(m => m[i].Count) @html.TextBoxFor(m => m[i].ArrivalTime) } } 

In this scenario, he spits out all the entries from the collection of technology. The question is how to make it display categories as labels and grouped vehicles under them.

• Category1
  • Technique1 - date and quantity input field
  • Technique2 - date and quantity input field
  • Technique3 - date and quantity input field
• Category 2
  • Technique4 - this technique has the second category, input field and dates
  • Technique5 - input field and date
