Navigation - Check If Children Are Visible

Using Umbraco And Getting Started

Umbraco 7
Hi All,

I'm looking for some help with filtering a navigation dropdown.

I have a umbracoNaviHide property on each document type. I want to be able to check if a level 3 child is visible.

Ive added .Where("Visible") to the if statement instead of Any(), but I get the error -

Cannot implicitly convert type 'System.Linq.IQueryable

Any help would be grateful.

Martin
```
 @foreach (var level3 in level2.Children.Where("Visible"))
    {
        if (level3.Children.Any())
        {
            <li class="has-children">
                <a href="#3">I Have Children</a>
            </li>
        }
        else
        {
            <li>
                <a href="">I Have No Children or All Children Are Hidden </a>
            </li>
        }
    }
```

Hi Martin

Use this code:

@foreach (var level3 in level2.Children.Where(x => x.IsVisible()))
{
    if (level3.Children.Where(x => x.IsVisible().Any())
    {
        <li class="has-children">
            <a href="#3">I Have Children</a>
        </li>
    }
    else
    {
        <li>
            <a href="">I Have No Children or All Children Are Hidden </a>
        </li>
    }
}

By the way, what is the type of level2?

Thanks,

Alex

Hi Alex,

Thanks for that.

Yeah my level 2 is just the same. I dont think i could use a helper, as each level has a different styling. So it was easier to just build out each level.
