如何将新属性设置为@ Html.DropDownListFor

Question

I'm trying to add an specific attribute (data-toggle="select") to my DropDownListFor.

When I use:

@Html.DropDownListFor(model, myList, "Select..", new { @class = "form-control", @data-toggle="select" }). 

I get the error saying that "Cannot resolve symbol 'data'" and "Cannot resolve symbol 'toggle'"

What can I do so my DropDownListFor recognizes the attribute data-toggle?

Ps: When I use

@Html.DropDownListFor(model, myList, "Select..", new { @class = "form-control"})

it works just fine

答案实际上很简单，只需将您的-（破折号）替换为_（下划线），便会被设置。

@Html.DropDownListFor(model, myList, "Select..", new { @class = "form-control", @data_toggle="select" }).
