title: Kendo Grid - row expand animation
body: <p>I'm using a kendo grid.
  I want to add a slide-down animation - when I click on a row in the grid it expands with animation 
  (the expansion happens with grid.ExpandRow function - kendo inner). </p>
  
  <p>I think that I need the animation on k-detail-row element. 
  But I still cant find the proper place/way to do that.</p>
  
  <p>Anyone did that already, and can help me with that.</p>
