     @Html.HiddenFor(m => m.SelectedReportId)

    @Html.HiddenFor(m => m.SelectedMatchTypeId)

    @Html.DropDownListFor(

            m => m.SelectedCompId,

            new SelectList(ViewBag.Comp,"CompetitionID", "CompetitionName"),

            new { Multiple = "multiple", @class = "multiselect", style = "width: 200px"}

<script type="text/javascript">
