Two column Free Flowing Layout in xaml wpf (MVVM)

I have a collection which I want to render as two or more column layout in xaml in my WPF appliaction.I dont wanna use grid columns as i dont want to fix the number of items in each column.Is there any way to do it with wrap panel,stack panel... etc.

I want something like this

  Mango    Orange       Basil
  Banana   Pomegranate  Tulsi
  Apple    Papaya       ....

Thanks in advance.
