Optgroup drop-down support in MVC - Problems with Model Binding

Question

I wonder if anyone can shed some light on this problem..

I\'ve got an option group drop-down for selecting a person\'s ethnicity – however it’s not storing the value in

Answer 1

This is supported natively using SelectListGroup as of ASP.NET MVC 5.2:

var items = new List(); 
var group1 = new SelectListGroup() { Name = "Group 1" };
items.Add(new SelectListItem() { Text = "Item1", Group = group1 }); 

Then in MVC, do

@Html.DropDownList("select", items)
