[Questions/Thoughts] Unity 4.6, the new UI system

I read this:
https://developers.google.com/web/fundamentals/layouts/rwd-patterns/column-drop?hl=en
and here their demo:
http://googlesamples.github.io/web-fundamentals/samples/layouts/rwd-patterns/column-drop.html
How can I do it? I try to use HorizontalLayoutGroup, VerticalLayoutGroup and GridLayoutGroup but can't achieve this.

 

Can't one just place everything in that layout? Or was there some sort of interactive component I missed?

 

Just one component in gameobject. When I put them together it cause weird result. The problem is I dont know how to make this:
http://googlesamples.github.io/web-fundamentals/samples/layouts/rwd-patterns/column-drop.html
with layout controller components. Or, the best way is I have to make it by script.

 

Use a layout grid, then add a script that changes the row / column settings based on Screen.Width / Screen.Height?
Should be like 20 lines of code

 

Thank you

 

Can Anyone please guide me I am using Unity 4.6 UI Canvas. The problem is that when I put my 3d Objects in canvas They does not show in game view and when I scale my 3d object then It shows in game view but they look too small in mobile build.
I am using the hierarchy of UI is
1 Canvas-parent
1.1 Panel - Child
1.1.1 My 3d Object

 

Probably because you scaled your canvas to something real small; try changing the canvas size itself.
