block

he {block} contents of a child template will replace the contents of {block}-s with the same name in the parent template(s).

Optionally {block} areas of child and parent templates can be merged into each other. You can append or prepend the parent {block} content by using the append or prepend option flag with the childs {block} definition. With the {$smarty.block.parent} the {block} content of the parent template can be inserted at any location of the child {block} content. {$smarty.block.child} inserts the {block} content of the child template at any location of the parent {block}.

{blocks}'s can be nested.
