How to Add Bootstrap Multi-level Dropdown Submenu in Drupal
Download and install a Bootstrap theme.
Modify the following at bootstrap/templates/menu/system/form-element.func.php:
/**
* Overrides theme_form_element().
*/
function bootstrap_form_element(&$variables) {
$element = &$variables['element'];
$name = !empty($element['#name']) ? $element['#name'] : FALSE;
$type = !empty($element['#type']) ? $element['#type'] : FALSE;
$checkbox = $type && $type === 'checkbox';
$radio = $type && $type === 'radio';
// Create an attributes array for the wrapping container.
if (empty($element['#wrapper_attributes'])) {
$element['#wrapper_attributes'] = array();
}
$wrapper_attributes = &$element['#wrapper_attributes'];
// This function is invoked as theme wrapper, but the rendered form element
// may not necessarily have been processed by form_builder().
$element += array(
'#title_display' => 'before',
);
