Hi guys,

I have an item with an item list on it (Images).

But when the item list is empty it still appears in Loops, so this:

@if (Loops.Contains("Item.Images")) {
<div>
  foreach here...
</div>
}

does not work to avoid my wrapping div beeing output... How do you do this in Razor?

Greetings. We really appreciate your appeal and will try to do anything to help you. 

Looks like there is no specific function to chekc if any item list items exists, but i can suggets you use next construction for it:

@if(!string.IsNullOrEmpty(GetString("Item.Images.Value"))){
   <div> foreach here... </div>
      }

I guess it will help you with your task. If not - add some details here and i'll try to help you.

What are you for-eaching over? Can't you check for Any() or Count == 0?
