How to edit a custom region from an Omega subtheme in Drupal 7 I created a new region in my Omega subtheme called MYTHEME-MENU. I want this region to do the same thing as the normal menu region, but with adding some markup. What is the proper way of doing this (I don't want to add the markup in Omega's region-menu.tpl.php file)?

I see I have a template, process and preprocess directories along with an empty template.php file, but I'm not sure how to use these. 

Essentially my MYTHEME-MENU region needs to spit out the following:

&lt;div&lt;?php print $attributes; ?&gt;&gt;
   &lt;div&lt;?php print $content_attributes; ?&gt;&gt;
&lt;span class="nav-bg"&gt;&lt;/span&gt;
    &lt;?php if ($main_menu || $secondary_menu): ?&gt;
    &lt;nav class="navigation"&gt;
    &lt;?php print theme('links__system_main_menu', array('links' =&gt; $main_menu,
       'attributes' =&gt; array('id' =&gt; 'main-menu', 'class' =&gt; array('links', 'inline', 
       'clearfix',     'main-menu')), 'heading' =&gt; array('text' =&gt; t('Main 
        menu'),'level' =&gt; 'h2','class' =&gt;     array('element-invisible')))); ?&gt;
    &lt;?php print theme('links__system_secondary_menu', array('links' =&gt; $secondary_menu,
       'attributes' =&gt; array('id' =&gt; 'secondary-menu', 'class' =&gt; array('links', 
       'inline', 'clearfix', 'secondary-menu')), 'heading' =&gt; array('text' =&gt; 
        t('Secondary menu'),'level' =&gt;     'h2','class' =&gt; array('element-
        invisible')))); ?&gt;
    &lt;/nav&gt;
    &lt;?php endif; ?&gt;
    &lt;?php print $content; ?&gt;
    &lt;/div&gt;
  &lt;/div&gt;
You don't need to create another region for that.

You just have to copy the Omega file omega/templates/region--menu.tpl.php
to your subtheme's template folder: MYTHEME/templates/region--menu.tpl.php.

There you can make whatever changes you need.
