Detailed explanation

The default layout type is NONE after adding the Layout component. It indicates that the container won't change size and location of the sub-object. When the user places sub-object manually, the container will take the minimum rectangular region that can contain all the sub-objects as its own size.

You can switch the layout container type by altering Type in Properties panel, all the layout types support Resize Mode.

When using Grid layout, the Start Axis is very important. When choosing Horizontal, it will fill an entire row before a new row is started. When choosing Vertical, it will fill an entire column before a new column is started.
