Dynaspan is an in place text editing solution for Rails with AJAX substituting text to an input field. Unlike other in place text editing solutions this is designed to support Rails forms with nested attributes. This gem does all the heavy lifting allowing you to write a simple method call to do all the work for you. It includes extra features such as JavaScript hooks, and complete options customization. A sample demonstration is available on the JS Fiddle link on the github repo. https://github.com/danielpclark/dynaspan
