If by frame you mean the HTML frames, then you will have 3 HTML pages
there (frameset + 2 frames), and each will be requested by the client
independently. That means, you will need (at least) 3 templates (or a
static HTML and 2 templates). That's how HTML and HTTP works,
FreeMarker can't do anything about it. I guess your problem here is
that while these 3 HTML-s rendered independently, in your application
they had to share matching data... Well, that's a problem you face
when using HTML frames, regardless of what view technology your are
using. Use Servlet sessions to store the data the individual HTML-s
should share, and/or code information into the URL-s of frames and
tree node links via query strings (or store the data in the farmeset
HTML and pull it into the two frames with JavaScript, but this last is
more tricky as it involves quite much of client-side work).

Another approach is not using HTML frames at all, but achieve
something like what you want with CSS tricks and AJAX... But that
solution surely requires the most skills.
