How Can I Conditionally disable the @HtmlEditorFor Based on Model Id ASP.NET Mvc 4

Question

I would like to conditionally disable this button, or hide it, if Model.Promotion.PromotionID is 10. Not sure how to do it. i am attempted to find the solution but struggling with it.

Would appreciate some help thanks

 @using (Html.BeginForm("Edit", "Promotion", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    @Html.HiddenFor(model => model.Promotion.PromotionID)

    @Html.HiddenFor(model => model.Promotion.Active)


    <fieldset class="fieldset">
        <legend class="legend">Edit Promotion</legend>

        <div>

        <div class="editor-field" title="The name of the Promotion"  @((Model.Promotion.PromotionID == 209) ? "disabled" : "")>
                    @Html.EditorFor(model => model.Promotion.PromotionTitle )
                    @Html.ValidationMessageFor(model => model.Promotion.PromotionTitle)
                </div>

                </div>
