MultiSelect cascade from DropDownList

[Jian]

We have two dropdowns, second one CascadeFrom the first, using MVC wrapper.  The second dropdown actually needs to be a MultiSelect.  MultiSelect doesn't appear to have a CascadeFrom option.  Please confirm that cascading is not possible with the new MultiSelect control.  Seems like that's something MultiSelect would support.  Any known workarounds?  Thanks.     

Here's the existing code, we're trying to make the second dropdown a MultiSelect

@(Html.Kendo().DropDownListFor(m => m.InputModel.CampusCode).OptionLabel("--- select ---").BindTo(Model.Campuses))

@(Html.Kendo().DropDownListFor(m => m.InputModel.RepUserCode)
      .DataTextField("FullName")
      .DataValueField("ClientUserCode")
      .DataSource(source =>
          {
              source.Read(read => read.Url("/GetCampusUsers);
              source.ServerFiltering(true);
          })
      .OptionLabel("-- select --")
      .AutoBind(false)
      .CascadeFrom("InputModel_CampusCode")
      )

Hello Jian,

 
Even that the MultiSelect does not support cascadeFrom option, you can manually implement the required functionality. On cascade event of the first dropdownlist just filter the dataSource of the multiselect. This jsFiddle demo shows how filtering can be implemented.
