Answer 1

You can also follow another approach which is to collect all dropdown lists in 1 helper class and return theses lists each with a static function.

Ex. Dropdown helper class

namespace Asko.Web.Mvc.Infrastructure.Utils
{
    public static class DropdownHelper
    {
        public static IEnumerable GetAllCategories()
        {
            var categories = category.GetAll();
            return categories.Select(x => new SelectListItem { Text = x.categoryName, Value = x.categoryId.ToString()}));
        }
    }
}

And here you are going to use it in the page:

      Category: 
      

 @Html.DropDownListFor(m => m.CategoryId, DropdownHelper.GetAllCategories())
