Print title of block group to allow for collapsible group
I'm about to do something similar, but I imagine you could do a preprocess and populate the variable yourself.

-- EDIT --

As a matter of fact, I am sure of it. Just did it myself.

In template.php write a hook_preprocess_region() function.

function mytheme_preprocess_region(&amp;$variables) {
  if ($variables['region'] == 'blockgroup_regionname') {
    $variables['title'] = 'Title';
  }
}


Then just in your template.

&lt;?php if ($title): ?&gt;
  &lt;h2 class="title"&gt;&lt;?php print $title; ?&gt;&lt;/h2&gt;
&lt;?php endif; ?&gt;


Which in turn should make the variable available to whatever else you are trying to do. SHOULD anyway. Good luck!
