title: Symfony2 templates/layouts
body: <p>I am new to symfony2 so please forgive me if this is a stupid question.</p>
  
  <p>Symfony2 is organised in bundles - so everything is a bindle right?</p>
  
  <p>Based on this I have created the following bundles in order to have a simple login mechanism:</p>
  
  <ul>
  <li>App
  <ul>
  <li>The main bundle will contain all global functionality </li>
  </ul></li>
  <li>User
  <ul>
  <li>Will be used to represent users</li>
  </ul></li>
  </ul>
  
  <p>So the bundles work correctly and all is fine.</p>
  
  <p>Now I cant figure out the best way to add a layout/theme structure to the site.</p>
  
  <p>I obviously need some global assets such as header, nav and foooter.  But additionally, there needs to be some global css style sheets, jquery etc.</p>
  
  <p>The most obvious place bundle is App - but how do i make all other bundles inherit the theme from this bundle.  For example, the user bundle template needs to extend the App bundle etc.</p>
  
  <p>The idea for bundles is that they are modular and self contained, therefore how can this be achieved</p>
