Tabs Helper

This plugin is a Ruby on Rails helper for tabbed interface with control of current tab and different styled tabs.
Very useful for web appications.

INSTALATION

  ruby script/plugin install git://github.com/danielvlopes/tabs_helper.git

USAGE

Just install the plugin and see the example below:

EXAMPLE

Controller

class DashboardController < ApplicationController
  current_tab :mydashboard
  ...
end

View

ERB code

<% tabs :id=>"mainMenu", :class=>"menu" do |tab| %>
  <%= tab.account 'Account', account_path, :style => 'float: right' %>
  <%= tab.users 'Users', users_path, :style => 'float: right' %>
  <%= tab.mydashboard 'Dashboard', '/' %>
  <%= tab.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>

Blocks for content

Also is possible to pass blocks instead of simple strings for content.
In this way you can create tabs with icons. Like below:

<% tabs do |tab| %>
  <% tab.account account_path do %>
		<%= image_tag "account.jpg" /> Accounts
  <% end %>
  <% tab.users users_path do %>
		<%= image_tag "user.jpg" /> Users
  <% end %>
  <% tab.posts posts_path do %>
		<%= image_tag "posts.jpg" /> Posts
  <% end %>
<% end %>

CSS and HTML

This plugin don’t came with any kind of asset like image or css. The layout of tabs and the way of show it depends of you css architecture. You can use any kind of technique with html UL and LI, like below:

<html>
<head>

<style type="text/css" charset="utf-8">
#header ul { font-family:Tahoma; position: absolute; margin:0; list-style:none; }
#header li { display:inline; margin:0; padding:0; }

#header a {
   float:left;
   background: url(corner_left.jpg) no-repeat left top;
   margin:0;
   padding:0 0 0 4px;
   text-decoration:none;
}
#header a span {
   float:left;
   display:block;
   background: url(corner_right.jpg) no-repeat right top;
   padding:4px 14px 4px 6px;
   color:#FFF;
}

#header a:hover span { color:#FFF; }
#header a:hover { background-position:0% -43px; }
#header a:hover span { background-position:100% -43px; }
#header #current a { background-position:0% -43px; }
#header #current a span { background-position:100% -43px; }

</style>
</head>

<body>
<div id="header">
     <ul>
          <li><a href="#"><span>Home</span></a></li>
          <li><a href="#"><span>Quem Somos</span></a></li>
