可以通过使用Html.DropDownListFor和Html.CheckBoxFor来创建一个包含复选框列表的下拉列表。以下是一个示例代码：

在ViewModel中添加数据模型：

public class MyViewModel { public string SelectedItem { get; set; } public List Items { get; set; } public List SelectedItems { get; set; } public List CheckBoxItems { get; set; } }

在Controller中添加数据：

public ActionResult Index() { var model = new MyViewModel(); model.Items = new List() { new SelectListItem() { Text = "Option 1", Value = "1" }, new SelectListItem() { Text = "Option 2", Value = "2" }, new SelectListItem() { Text = "Option 3", Value = "3" }, new SelectListItem() { Text = "Option 4", Value = "4" } };

model.CheckBoxItems = new List()
{
    new SelectListItem() { Text = "CheckBox 1", Value = "1" },
    new SelectListItem() { Text = "CheckBox 2", Value = "2" },
    new SelectListItem() { Text = "CheckBox 3", Value = "3" },
    new SelectListItem() { Text = "CheckBox 4", Value = "4" }
};

return View(model);

}

在View中添加HTML：

@model MyViewModel @using (Html.BeginForm()) { @Html.DropDownListFor(m => m.SelectedItem, Model.Items, new { @class = "form-control" })

@Html.CheckBoxFor(m => m.SelectedItems[0], Model.CheckBoxItems[0].Text, new { @class = "checkbox-inline" })
@Html.HiddenFor(m => m.CheckBoxItems[0].Value)

@Html.CheckBoxFor(m => m.SelectedItems[1], Model.CheckBoxItems[1].Text, new { @class = "checkbox-inline" })
@Html.HiddenFor(m => m.CheckBoxItems[1].Value)

@Html.CheckBoxFor(m => m.SelectedItems[2], Model.CheckBoxItems[2].Text, new { @class = "checkbox-inline" })
@Html.HiddenFor(m => m.CheckBoxItems[2].Value
