has_breadcrumbs

has_breadcrumbs is a simple plugin that adds a breadcrumb object into controllers and views.

Instalation

1) Install the plugin with `script/plugin install git://github.com/danielvlopes/has_breadcrumbs.git`

Usage

On your controller:

class ApplicationController < ActionController::Base
	before_filter :add_initial_breadcrumbs

	private
		def add_initial_breadcrumbs
			breadcrumb.add 'Home', root_path
		end
end

class ThingsController < ApplicationController
	def index
		breadcrumb.add 'Things', things_path
	end
end

You don’t need to provide an URL; in that case, a span will be generated instead of a link:

breadcrumb.add 'Some page'

You can set additional HTML attributes if you need to:

breadcrumb.add 'Home', root_path, :id => 'home', :title => 'Go to the home page'

On your view (possibly application.html.erb):

You are here: <%= breadcrumb.display %>

You can set your own separator:

You are here: <%= breadcrumb.display %>

The output in your html will be something like below:

	<ul id="breadcrumbs">
		<li class="item-0"><a href="#">Home</a></li>
		<li class="item-1"><a href="#">Main section</a></li>
		<li class="item-2"><a href="#">Sub section</a></li>
		<li class="item-3 last">The page you are on right now</li>
	</ul>

For a good css example take a look in examples folder.
