Area groups

Permalink
Hi!

I'm new to concrete and i try to create my first site with it.

Now i've a problem, with the CMS i used before it was possible to group areas, so it was possible to add for example 2 Blocks (text left, image, or video on the right) to one "area group".

Example:http://www.magentocommerce.com/product/enterprise-edition...

How i can create something like that?
Or is it necessary to create for every combination of types (text, image, ... ) a custom block-type?

Thanks, Bernie
