title: WPF: multi-column listbox / listview?
body: <p>I'd like to create a list in WPF that displays data in several columns, like Explorer display a list of files in 'Small icons' view mode:</p>
  
  <p><img src="https://i.stack.imgur.com/sSnLg.png" alt="Multi-column list box"></p>
  
  <p>Each item must be represented by a <code>DataTemplate</code> and the scrolling is supposed to be horizontal. How do I make such a list?</p>
