Show/Hide regions in Omega subtheme I am using Drupal 7 and I am creating an Omega subtheme.

In my case I want a page without left and right sidebars. But when I inspect the page.tpl.php from alpha theme it contains only code for printing attributes, content and footer regions

Here is my page.tpl.php

print $attributes;
  if (isset($page['header']))

   print render($page['header']);

  endif; 

 if (isset($page['content']))

    print render($page['content']);

 endif;

  if (isset($page['footer']))

     print render($page['footer'])

  endif;


In the above snipped I don't find any option to show/hide sidebars as we used to do like in Garland theme.
You can create multiple page layouts using delta modules and use the same for required page.
