how to use with automodal class?

Hmm. As of right now feedback_simple does not support this, but this is a great idea. I'll add class support right now.

Here's a quick patch to add this functionality...

To enable this for automodal you could either a) Set the Automodal CSS selector to 'feedback_simple' at admin/settings/automodal or b) Hook into the theme layer.

Here is how you could hook into the theme layer. Add this to your custom module or theme:

/**
 * Implements hook_preprocess_feedback_simple().
 */
function MYMODULEORTHEME_preprocess_feedback_simple(&$variables) {
  // Add .automodal class.
  $variables['class'][] = 'automodal';
}

Alternatively,

Just download this module and enable it. :)

Issue summary.

After some limited testing it is working as desired except the issue of the Feedback tab showing up in the modal. I've created a separate issue for this at: #1246994: Hide the tab when on the $link page.

Final solution to those looking to implement this.

Update feedback_simple to at least version 6.x-1.2 and then download and enable the module from #4 OR provide the preprocess from #3 in your module or theme.
