By cells do you mean nesting nodes within each other? This is done simple by taking a node and dropping it in another node, in this case they've changed the shape of the child nodes to rectangles so they look like one line cells within the parent. So if you have 2 nodes on the map select one and drag it over the other and drop the node and it will be come a child.
