Adding area to product info page

If you look at the following link, I would like to add another area similar to 'please choose required components' called something like 'additional items you may wish to add'

http://www.flamedepot.com/index.php?...roducts_id=193

Is it possible to do this and if so, how would I go about it?

Thanks in advance!

You might be able to do this in Option Names Manager - edit a name and find the capacity to add a comment. This comment could be associated with the first attribute you want in the additional section.

I'll have to look at it more closely to see what tweaks might be needed to make this work fully.

create a text attribute name with a value of the text you want - this is display only and a sort of "0" so it is first

Have you looked at "cross sell" modules? (see downloads section)
