I am curious about something and I need some recommendations as my best route to take

I need to have a list on the right side of the page that is scrollable and it will be a long list of 50 names that are linked. I would set this div to have overflow: auto

Then on the right side of the page (or content section) will be another scollable pane where the results of whatever is clicked on the left will show up.

Naturally, this screams out I-frame. But I am not sure if I can set that to overflow: auto also and then have the results from the link clicked show up in there or not.
