The Forme demo site is part of the forme
repository: https://github.com/jeremyevans/forme/tree/master/demo-site
You are right that the form options/template code sections are overly terse
for most of the basic examples. That's due to the fact that the basic
examples all use the same template code, and the only difference is the
options used. This is a double edged sword, showing how flexible Forme is,
but being very hard to learn from. It really should focus more on teaching
people how to use Forme.

The :as options are documented briefly in the README. They are also
documented in the method RDoc, but for private methods, so they don't show
up in the documentation unless you use rdoc -V private. However, even that
probably doesn't show all of the available options. In general, Forme is
lacking in documentation, so looking at the specs is probably the best way
to see what is supported.

As explained in the README, :as=>:radio only works for many_to_one
associations. For a custom enumerated type, you can use :type=>:radio, but
that produces a single radio input. For multiple radio inputs, you need to
loop over the options and create a radio input for each option. If you
want a select box with multiple options, you can do that with a single call:
f.input(:field, :type=>:select, :options=>%w'value1 value2 value3')
If you have more questions, please let me know. I know Forme could benefit
from better documentation and general polish, but as it still isn't very
popular, I don't devote much time to it. I realize this is a chicken and
egg scenario. I would love additional help with Forme, so if it's
something that interests you, please do send pull requests or get in touch
with me via email or IRC to discuss your ideas. Replying here is fine as
well.
Thanks,
Jeremy
