title: Android "Top Sheet" equivalent of "Bottom Sheet"?
body: <p>I am wanting to implement a "Bottom Sheet" type of layout, but with a twist where the "bottom" sheet will be a MapFragment, which won't work very well as an up/down draggable view.</p>
  
  <p>I had a probably naive thought to "flip" the logic to a "Top Sheet" design, where you drag the Top Sheet up/down to show more/less of the bottom MapFragment.</p>
  
  <p>ie: From this...<br>

  <p>...to [something like] this...<br>

  <p>Is this possible given the Support Design Tools, or will I have to roll something like this on my own?</p>
