= menu_builder

A simple helper + controller macro to make easier to highligh menu items based on actions (instead of urls)

== Instalation

  gem "menu_builder"

== Usage

=== Controller

  class DashboardController < ApplicationController
    menu_item :mydashboard
    ...
  end

You can also change to menu item at action level instead of class level.

  class DashboardController < ApplicationController
    menu_item :mydashboard

    def prices
      menu_item :prices
      ...
    end
  end

And you can prepend or append just one item to the collection

  class DashboardController < ApplicationController
    menu_item :mydashboard

    def prices
      append_menu_item :prices
      ...
    end
  end

=== View

==== ERB code

  <%= menu(:id=>"mainMenu", :class=>"menu") do |m| %>
    <%= m.account 'Account', account_path, :style => 'float: right' %>
    <%= m.users 'Users', users_path, :style => 'float: right' %>
    <%= m.mydashboard 'Dashboard', '/' %>
    <%= m.projects 'Projects', projects_path %>
  <% end %>

==== HTML Result

   <ul id="mainMenu" class="menu">
     <li><a href="/accounts">Account</a></li>
     <li><a href="/users">Users</a></li>
     <li><a href="/" class="current">Dashboard</a></li>
     <li><a href="/projects">Projects</a></li>
   </ul>
