Answer 1

1.Change @Html.Partial("_GuestNav") to @{Html.RenderAction("_GuestNav", "YourControlerName");}

2.Add @Model TypeofYourViewModel on top of your partial view.

3.Change the looping as follows:

@foreach (var item in Model)
    {
        <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">@item.MainCatName<span class="caret"></span></a>
            <ul class="dropdown-menu" role="menu">
                @foreach (var subcat in item.subcat)
                {
                    <li><a href="#">subcat.SubcatName</a></li>
                }
            </ul>
        </li>
    }

Note: Change TypeofYourViewModel to whatever ViewModel you are passing into the partial view
