title: UICollectionView special horizontal flow - multiple sections
body: <p>I have a UICollectionView there is used differently depending on device orientation. The image describe what I have and what I need. </p>
  
  <p>Is it possible to get "Horizontal scrolling as I need it" with default flowlayout or do I need to make customflowlayout(Guide appreciated) or multiple collectionviews?</p>
