How to MVC 5 drop down (multiple select) box
<p>I'm having trouble with this drop down box, just cant seem to get it right, here's the code:</p>

<p>View (Index.cshtml):</p>

<pre><code>@using EvaSimulator.Models
@Model EvaSimulator.Models.ModelVariables
@{
    ViewBag.Title = "Index";
    ModelVariables mv = new ModelVariables();
}
@using (Html.BeginForm("DropDownBox", "Home", FormMethod.Get))
{
    @Html.DropDownList("dropdownbox", )
    &lt;button type="submit"&gt;&lt;/button&gt;
}
&lt;p&gt;@Model.dropDownList&lt;/p&gt;
</code></pre>

<p>Model (ModelVariables.cs):</p>

<pre><code>public string dropDownList = "";
</code></pre>

<p>Controller (HomeController.cs):</p>

<pre><code>public ActionResult DropDownBox(string dropdownbox)
{
    ModelVariables mv = new ModelVariables();
    mv.dropDownList = dropdownbox;
    return this.View("Index", mv);
}
</code></pre>

<p>This just doesent look right, and I'm only looking for a simple solution, create a drop down multiple select list box and whatever I submit, I get the list of values and print them in <code>&lt;p&gt;</code> tag in the view (<code>@Model.dropDownList</code>)</p>
