rails_nestable_layouts's Introduction

Rails Nestable Layouts

Dead simple nested layouts support for Rails. Does not monkey patch anything. Can nest as many layouts as desired.

Install

gem 'rails_nestable_layouts'

Usage

Your Controller

# main layout, this line is not necessary. Note nested_layouts does not override the main layout.
layout :application 

# accepts the same options as before_action/before_filter
nested_layouts 'layouts/secondary_layout', 'posts/layout', except: [:index]

Main Layout

<html>
  <head></head>
  <body>
    <h1>My Main Layout</h1>
    
    <!-- this will call the first nested layout , will fallback to normal functionality if no nested layouts. -->
    <%= yield_nested %> 
  </body>
  <footer></footer>
</html>

Nested Layout(s)

<h2>My Nested Layout</h2>

<%= yield_nested %> # this will call the next nested layout or the requested template if no more nested layouts.
