Thanks tom, let me try to explain a little more clearly.
I am using a looping section in one of my templates to display a product list (loops on db getting info). I do not want to just leave the results in a table because as I add more products then the page will get longer and longer. I don't really want to add the complexity of a next/prev page system (trying to keep this as simple as possible) and I cannot use an IFRAME as my template system will not pickup on variables in that (because the iframe contents will be in prodlistframe.tpl but the template system only parses prodlist.tpl which would hold the <iframe> tags).
So Ideally I would like to have an iframe look/function (embedded frame with scroll) BUT not using another file to get the source for the contents of the frame. I have been looking for 24h now and seen nothing like this so I guess it musn't be possible 🙁
I hope I explained more clearly this time.
