Enhanced DropDownListFor
The DropDownListFor Html extension available in the Data Moving Plug-in allows separate styles for each item and grouping of items with the <optgroup> tag. Moreover, the fields working as value and text fields are specified through lambda expressions (thus, taking advantage o syntactic checks and Visual Studio IntelliSense), instead of strings.
Below an example of usage:
Html.DropDownListFor(m => m.Roles,
new {style="height:100px"},
ChoiceListHelper.CreateGrouped(RegisterModel.AllRoles,
m => m.Code,
m => m.Name,
m => m.GroupCode,
m => m.GroupName,
m => new {style="color:White; background-color:Black"},
m => new { style = m.Code%2 == 0 ?
"color:Blue; background-color:White":
"color:Red; background-color:White"} ))
The result is:
