Accordion does not work

Same problem!

I have the same problem. I know the issue has to do with the id that is not set on the $element. The anchor tag does not have the proper fragment identifier on it (as there is no id to build it from), and then the content div does not have the id attribute that the anchor fragment references. Hence jQuery UI cannot function properly.

I have a shoddy workaround as I cannot trace where the id is supposed to be set. (It is not the id that is set on the gear popup form for the accordion group. That id is for the outer container.)

This is what I do in bootstrap_fieldgroup.module:

function field_group_pre_render_bootstrap_accordion_item(&$element, $group, &$form) {
$element['#id'] = drupal_html_id('bs-accord-' . rand(0, 9999)); // add this line
