The Rails documentation doesn't seem to mention this, but it's possible to add your own custom HTML attributes to the option tags generated using options_for_select

In our case, we wanted to add custom HTML5 data attributes to our options tags we could use unobtrusive javascript to notice when the the user made a new selection and update another part of the page with the contents of the selected option tag's data attribute

I found someone else actually recommend doing a copy/paste/rewrite of options_for_select, but if you dig into the Rails code a bit you'll find this is totally unnecessary. This is from form_options_helper.rb

• the two methods that get called on each element of the array you pass to

# install all the packages required for using ruby on rails in cygwin
# http://software.jessies.org/salma-hayek/cygwin-setup.html
# Cygwin is a Linux-like environment for MS Windows. You can read more about it on the Cygwin home page, but this page assumes you know what it is and have already decided that you want it. If you're a Unix user and you're stuck with a Win32 box, you probably do. It's quite a remarkable hack.

Download the Cygwin setup.exe from http://www.cygwin.com/setup.exe

# Packages
inetutils  # telnet(1)
ncurses    # see Terminator FAQ
openssh    # SSH (client and server, though the server's not so great)

For bundler I did the following on Catalina

$ brew install v8@3.15
$ gem install libv8 -v 3.16.14.15 -- --with-system-v8
$ gem install therubyracer -v 0.12.2 -- --with-v8-dir=/usr/local/Cellar/v8@3.15/3.15.11.18_1
$ bundle install
