Convert a Select Drop-Down Box to an Autocomplete in Rails

Mark Berry October 30, 2012

I created a nice select drop-down box in Ruby on Rails 3.2.8 using SimpleForm 2.0.2 and Twitter Bootstrap 2.0.3, with authentication from CanCan 1.6.8.

Since it’s Rails, it’ll be an easy change, right? Hoo boy.
