Have you looked at erb
(http://ruby-doc.org/stdlib/libdoc/erb/rdoc/...) or the CGI
standard library (http://ruby-doc.org/stdlib/libdoc/cgi/rdoc/...)?

Or do you mean parsing the HTML and making into that code?

Go to http://api.rubyon... and click on the Method named
"collection_select". It does just what you want.

Why not use a check box? I always hated drop downs for binary state
variables.
