How to render a 2nd level for MegaNav with Models Builder

The following code works for me in rendering a single level mega menu with Models Builder...

    @{
        if (Model.HasValue("MytopNav"))
        {
            <ul>
                @foreach (var item in Model.MytopNav)
                {
                    <li class="dropdown">
                    @item.Title
                      @*check for child links here*@
                    </li>
                }
            </ul>
        }
    }

But if any of my parent level li's have child links, how do I check for that and add it to this logic?

Hi blackhawk,

You can just check for children in each loop and then do another loop inside, something like this:

@{
    if (Model.Content.HasValue("MytopNav"))
    {
        <ul>
            @foreach (var item in Model.MyTopNav)
            {
                <li class="dropdown">
                    @item.Title
                    @*check for child links here*@

                    @if (item.Children.Any())
                    {
                        <ul>
                            @foreach (var child in item.Children)
                            {
                                <li>@child.Title</li>
                            }
                        </ul>
                    }
                </li>
            }
        </ul>
    }
}

Thanks for the help! I only had to change Children() to Children.

Ah, so close! I had thought it was that actually but my Visual Studio told me otherwise. Strange, updated my answer to match however.
