    limited list - see all link

    Hi,

    I need to show subitems of a node. A simple foreach would do the trick. But i need a limited amount. Max 5 items. If there are more the 5 items it should show a "see all" link.(parent node). If only 3 subitems, the "see all" node should not bu shown ofcourse. Working in v8

    Any help appreciated!

    You could use a simple counter variable, like so - and then apply whatever logic you need based on this. For example, if the counter is 5, then show "see more".

    @{
    int counter = 1;

    foreach (var i in Model.Children)
    {
        // Apply your own logic based on the counter
        // e.g - if counter == 5, show see all

        counter++;
    }
}

    Hi Josker

    How about this?

    @foreach (var child in Model.Children.Take(5))
{
  // show the node
}
@if (Model.Children.Count() > 5)
{
  <a href="/show-all-link">Show all</a>
}

    Hi Søren,

    Exactly how I did it! I was under the impression that the Take() only works if there are more items. But I was wrong. Thanks!
