Cannot move canvas or change any transform values

Question

I am using Unity 5 and I started creating a menu scene. When I made the canvas, all values ​​under the component are Rect Transformlocked, and it says "some values ​​controlled by Canvas." The only thing I can change is the z position when using gizmo in the editor. I can not reset the position or something else. Why is this happening?

Answer 1

This means that the canvas canvas component render modematters Screen space - overlay. This makes it be the size of the screen. Change it to World Spaceand it will allow you to resize it and move it.
