Project status: abandoned. This isn't compatible with recent versions of Ruby On Rails and there are now many other options that work better.
This project was started to learn Ruby, Ruby on Rails, and dynamic HTML techniques. I went on to refine it for general use, but then started a new job that prevented me from spending any more time on it.
Note: I'm afraid that this project is essentially abandoned. While I would love to do more work on LiveTree and with Rails in general, my life has gotten busier and there just isn't time. I won't be much use answering questions about using it either because it's been so long since I've looked at the code. If anyone would be interested in taking over the project, I have some half-finished and buggy code for some new features, as well as a few patches that users have sent, that I would be happy to provide. Also, if anyone has good suggestions for alternative tree controls for Rails that I can link to here, please send them in.
