Usage¶ ↑

After installation run the generator to place default stylesheet and javscript code (jQuery):

script/generate easy_navigation

To create your menus create config/initializers/easy_navigation.rb file like this:

EasyNavigation::Builder.config do |map|
  map.navigation :default do |navigation|
    navigation.tab :home, :url => { :controller => "/dashboard", :action => "index"} do |tab|
      tab.menu :index, :url => { :controller => "/dashboard", :action => "index" } do |menu|
        menu.connect :controller => "dashboard"
      end
    end
    navigation.tab :contacts, :url => { :controller => "/contacts", :action => "index" } do |tab|
      tab.menu :index, :url => { :controller => "/contacts", :action => "index" } do |menu|
        menu.connect :controller => "/contacts"
        menu.connect :controller => "/contacts/people", :except => "new"
        menu.connect :controller => "/contacts/companies", :except => "new"
      end
      tab.menu :new_person, :url => { :controller => "/contacts/people", :action => "new" } do |menu|
        menu.connect :only => "new"
      end
      tab.menu :new_company, :url => { :controller => "/contacts/companies", :action => "new" } do |menu|
        menu.connect :only => "new"
      end
    end
    navigation.tab :admin, :url => { :controller => "/admin/users", :action => "index" } do |tab|
      tab.menu :index, :url => { :controller => "/admin/users", :action => "index" } do |menu|
        menu.connect :except => "new"
      end
      tab.menu :new, :url => { :controller => "/admin/users", :action => "new" } do |menu|
        menu.connect :only => "new"
      end
    end
  end
end

As an example, to render you newly created menu called :default in your “layout/application.erb”:

<%= easy_navigation :default, options = {} %>

Internationalization (i18n)¶ ↑

If you want to use internationalization, set the option :i18n => true like this:

EasyNavigation::Builder.config do |map|
  map.navigation :default, :i18n => true do |navigation|
  ...
  end
end

For internationalization, edit your “en-US.easy_navigation.yml” file like this:

en-US:
  navigation:
    default:                  # The name of your navigation menu
      home:                   # The name of your tab
        title: "Home"         # The title of your tab
        menus:
          index: "Dashboard"  # The title for index action menu
          new: "New Page"     # The title for new action menu

Helper Options¶ ↑

:i18n             => Set to "true" to use i18n internationalization.
:navigation_class => Sets the class name for navigation menus (default: navigation).
:tab_class        => Sets the class name for tabs (default: tab).
:menu_class       => Sets the class name for menus (default: menu).
:separator_class  => Sets the class name for separators (default: sparator).
:separator        => Place a separator after each menu (default: false)

Render Customization¶ ↑

You may wan’t to change the way that the navigation menu gets rendered, if so simply override the following methods (from EasyNavigation::Helper):

Navigation Menus¶ ↑

def render_navigation(id, tabs_html, class_name)
  content_tag("ul", tabs_html, :id => id, :class => class_name)
end

Tabs¶ ↑

def render_empty_tab(id, text, url, class_name)
  content_tag("li", link_to(text, url, :class => 'tab_link'),
    :id => id, :class => class_name)
end

def render_tab(id, text, url, menus_html, class_name)
  content_tag(:li, "#{link_to(text, url, :class => 'tab_link')} #{content_tag(:ul, menus_html, :id => "#{id}_menus", :style => "display:none;")}",
    :id => id, :class => class_name)
end

Menus¶ ↑

def render_menu(id, text, url, class_name)
  content_tag("li", link_to(text, url, :class => "menu_link"),
    :id => id, :class => class_name)
end

Separators¶ ↑

def render_separator(class_name)
  content_tag("li", "|", :class => class_name)
end
