This gem packages the jsTree plugin for easy use with the Rails 3.1+ asset pipleine.
Add the following line to your Gemfile:
gem 'jstree-rails', :git => 'git://github.com/xinlangzi/jstree-rails.git'
then run bundle install and restart your app.
jsTree needs to be included after jQuery in your javascript manifest:
//= require jquery
//= require jquery_ujs
//= require jstree # add this line to app/assets/javascripts/application.js
//= require_tree .
Add the stylesheets to application.css:
*= require jstree-themes/default/style
Ideally, all your stylesheets should be concatenated and loaded in as few requests as possible. However, jsTree prefers to use its themes plugin to load a theme's stylesheet. I'm hoping to address this inadequacy at some point but, in the mean time, the theme folder has been preset to the correct path using $.jstree._themes = '/assets/jstree-themes/';.
Use themes the way you normally would but DON'T specify a URL:
// CoffeeScript
jQuery ->
$('.tree').jstree
plugins:
['themes']
themes:
theme: 'apple'
