Some parent components may have special representation for groups like adding separators around the group but this is a special case and is not always rendered this way.
In most cases, only the children of the group will be rendered directly to the page.
There will be no layout applied to the children so the natural layout behavior of the underlying HTML elements will apply.
If you require a more predictable layout, you should use a layout component such as panelGroupLayout."/>
