html <frame> tag not work

I want to make a view containing the <frameset><frame> tag to let the
part to accommodate enough info.But the rails does not support the
tag.So how do i get a element that has a scroll bar?
Thank you.

The first and obvious question is... why?! Frames should only be used
if you're including another page. Otherwise, not sure why you'd need
to do that.

RHTML files allow you to use any standard html code you want. Rails
doesn't provide this as a helper because it's hardly used anymore.
