title: Is there a ListRowPresenter which uses VerticalGrid instead of HorizontalGridView?
body: <p>As you know in leanback library there is a <code>ListRowPresenter</code> which presents its items via <code>HorizontalGridView</code>. (see its source <a href="https://raw.githubusercontent.com/home-tomonori-ishizaki/Android-Support-Leanback-v17/master/android/support/v17/leanback/widget/ListRowPresenter.java" rel="nofollow noreferrer">here</a>) But can we have a Presenter using <code>VerticalGrid</code>?</p>
  
  <p>I want the last row of my <code>BrowseFragment</code> becomes vertically scrollable (with how many rows as it need and fixed column number!) and instead of <code>setNumRows</code> I would write <code>setNumVolumns</code> ...</p>
  
  <p>Is it possible in leanback?</p>

  <p><strong>UPDATE 1 :</strong>
  In order to use a presenter in <code>BrowseFragmen</code>t, it should be a child of <code>RowPresenter</code>. <code>VerticalGridPresenter</code> is not so you can not use it in a browse fragment at all. I am looking for a something like <code>ListRowPresenter</code> which is built using <code>VerticalGridView</code>. (<code>ListRowPresenter</code> uses <code>HorizontalGridView</code>)</p>
