I am a beginner with Roku. I am attempting to create an SDK Roku channel, and want to create labels on the main screen that are categories. When you click the categories, I would like for it to be able to use a json feed to create a grid category like hero grid. For example, if the Label says Music, and you click it, I want it to use a json feed to create a grid that shows categories for music being (rap, country, jazz, pop, etc).
My json feed currently works for the nonsdk but can't seem to get the sdk to work for anything except a single row.
