Hide breadcrumb from CMIS views
CMIS Browser, a submodule of CMIS API, handles CMIS links. We are using CMIS API v7.x.x.
Here's the function responsible for the breadcrumb:
# cmis/cmis_browser/cmis_browser.theme.inc #125

function theme_cmis_browser_browse_breadcrumb($variables) {

  $next_img = theme('image', array('path' =&gt; drupal_get_path('module', 'cmis_browser') .'/images/next.gif'));
  $contents = '';
  $currentpath = '';

  $contents .= '&lt;div id=&quot;cmis-breadcrumb&quot;&gt;';
  if (!empty($_GET['type']) &amp;&amp; $_GET['type'] == 'popup') {
    $contents .= l('Root', 'cmis/browser'. $currentpath, array('query' =&gt; array('type' =&gt; 'popup', 'caller' =&gt; $_GET['caller'])));
  }
  else {
    $contents .= l('Root', 'cmis/browser'. $currentpath);
  }

  $currentpath = '';
  foreach ($variables['bcarray'] as $space) {
    $contents .= $next_img .' ';
    $currentpath .= '/'. $space;
    if (!empty($_GET['type']) &amp;&amp; $_GET['type'] == 'popup') {
      $pagelink = l($space, 'cmis/browser'. $currentpath, array('query' =&gt; array('type' =&gt; 'popup', 'caller' =&gt; $_GET['caller'])));
    }
    else {
      $pagelink = l($space, 'cmis/browser'. $currentpath);
    }
    $contents .= $pagelink;
  }

  $contents .= '&lt;/div&gt;';

  return $contents;
}

Our workaround is simply to return an empty &lt;div&gt; earlier:

function theme_cmis_browser_browse_breadcrumb($variables) {
  return '&lt;div id=&quot;removed-breadcrumb&quot;&gt;&lt;/div&gt;';
  
  .....
}

Be careful since it's not a persistent solution.
