Displaying parent nodes in Razor menu when no child nodes exist
Hey all,

I feel this is a simple task, however, I'm battling to get my head around this. I have a sub-menu which I'm converting from XSLT to Razor. The code simply lists any child nodes that exist under the parent.
```
@inherits umbraco.MacroEngines.DynamicNodeContext

<ul>
    @foreach (var item in @Model.Children.Where("Visible"))
    {
        <li><a href="@item.Url">@item.Name</a></li>
    }
</ul>
```
What I'm trying to do is adjust the code so that when no child exists under a node the parent nodes persist so, in effect, the sub-menu doesn't disappear.

Could anyone provide any code pointers please?

Many thanks,
Mike

Hi Mike

Try doing something like
```
@if(@Model.Children.Where("Visible").Count() > 0) {
//// either make your loop or display parent name 
}
```
Is this what you are trying to achieve here ?

Hi Fuji,

Yeah this is definitely along the right sort of lines. So this is what I've written. It works but I'm not sure it is the best way of writing it:

@inherits umbraco.MacroEngines.DynamicNodeContext
    @{
        var currentPage = Model;

        <ul>
            @foreach (var item in currentPage.Children.Where("Visible"))
            {
                <li><a href="@item.Url">@item.Name</a></li>
            }

            @if(currentPage.Children.Where("Visible").Count() == 0) {
                foreach (var item in currentPage.Parent().Children.Where("Visible")) {
                    <li><a href="@item.Url">@item.Name</a></li>
                }
            }
        </ul>
    }

So basically the menu shows any child links that are available and visible until it can't find any more children, at this point the menu should show and persist a list of the children at its parent level - i.e. the menu doesn't just disappear off the screen.

Is there a more efficient way of writing the above? Like I say, it works but is it the best way?

Many thanks,
Mike
