    Hi Rizwan

    There is a couple of ways you can go with this and it depends on the type of pages the 'children' are.

    IF all your children of the parent page are of the same type, let me say they are all of 'BlogPost' type and have a NestedContent property called 'Authors' then you could change your foreach loop to be

    @foreach (var child in Model.Children().OfType<BlogPost>()){
    foreach (var author in child.Authors){
    <h2>@author.Name</h2>
    @author.Value<IHtmlString>("biog")
    }
    }
    

    The 'OfType' is casting all the children of the page to be of the generated Modelsbuilder type 'BlogPost' and an underlying PropertyValueConverter has helpfully turned the NestedContent property into a collection of Authors you can loop through.

    If you have 'different' types of pages underneath the parent, then you could either make sure the different types of pages implement a common interface, or you could work with what .Children returns by default, eg an IEnumerable of IPublishedContent elements, it would look something like this:

    @foreach (var child in Model.Children){
    foreach (var author in child.Value<IEnumerable<IPublishedContent>>("authors")){
    <h2>@author.Name</h2>
    @author.Value<IHtmlString>("biog")
    }
    }
    

    You can see without 'OfType' we are having to fish for the properties by 'alias', so there is more to type, and more chance of typos!

    regards

    Marc
