I have a project using dojo dnd, that allows users to drag and drop "web elements" onto a page to create a simple page.

I would like to take this base project to the next level, specifically in two areas:

1. at the moment the drag and drop elements are "full width" blocks that can be dragged above or below each other. I would like the drag and drop to work more in a grid fashion, so elements could be dragged left/center/right as well as up and down....

2. I would like to also create some kinda hierarchical drag and drop function, to show relationship of pages (ie home page , cat page linked to home, sub cat page linked to cat page etc....)
