Sections in MarkupGrid (SceneGraph)

The docs for MarkupGrid state that to create sections a ContentNode with a contentType of “SECTION” should be created, with the item or content nodes contained as children of the section node. However, attempting to set the contentType to “SECTION” on a ContentNode returns the error “Error setting the “ContentType” field of a “ContentNode” node”.

I believe that this is because a contentNode’s ContentType can only be set to certain pre-defined strings (from the Docs for ContentNode: “Valid values = movie, episode, season, series, audio”). If that is the case, how can sections be created for a MarkupGrid?

Hi,
Can someone pls confirm if the sections work for markupgrid? Is there any code sample?

Horizontal scroll in not working on markup grid. Can some one let me know how the horizontal scroll works on mark up grid. Like, I want to hide the left columns when I scroll right and similarly show them when I scroll left on the grid.
