Hi Ben,

You're right, the sample is incorrect.

Try this:

        if (Model.Content.HasValue("testDropdown"))
        {
            <ul>

                @foreach (var item in Model.Content.GetPropertyValue<IEnumerable<string>>("testDropdown"))
                {
                    <li>@item</li>
                }
            </ul>
        }

If you are using the models builder, it is simply:

                @foreach (var item in Model.Content.TestDropdown)
                {
                    <li>@item</li>
                }
