No, DW doesn't support Frames anymore and for good reason. Frames are no longer supported in HTML5 web standards. Frames are not mobile/tablet friendly. Frames are Evil. Just don't use them, ever.
or a way around it
Why can't you just add your frames in code view?
Please don't tell me your html class still teaches you to use frames!?! Avoid like the plague.
If that topic is still part of any curriculum, my advice is to run away. Fast.
