Open a specific horizontal tab on page load but without page jumping to the anchor

I would appreciate the same feature. I need a link to particular tab.

Hello,

I started working on adding anchors to horizontal tabs. The following code allows the admin to attach a custom id to a fieldset.

Could you please implement this code to the dev version of Field group?
file field_group.module

function field_group_field_group_format_settings($group) {
// ...
    case 'htab':
	  $form['instance_settings']['custom_id'] = array(
		'#title' => t('Custom id'),
		'#type' => 'textfield',
		'#default_value' => isset($group->format_settings['instance_settings']['custom_id']) ? $group->format_settings['instance_settings']['custom_id'] : (isset($formatter['instance_settings']['custom_id']) ? $formatter['instance_settings']['custom_id'] : ''),
		'#weight' => 0,
	  );
    case 'accordion-item':
    default:
  }

  return $form;
}

file field_group.module

function field_group_field_group_pre_render(& $element, &$group, & $form) {
// ...
  if(isset($group->format_settings['instance_settings']['custom_id'])) {
	  $element['#id'] = $group->format_settings['instance_settings']['custom_id'];
  }
  elseif (isset($group->format_settings['instance_settings']['id']) && !empty($group->format_settings['instance_settings']['id'])) {
    $element['#id'] = $group->format_settings['instance_settings']['id'];
  }
  else {
    $element['#id'] = $form['#entity_type'] . '_' . $form['#bundle'] . '_' . $view_mode . '_' . $group->group_name;
  }
// ...

The next step should be modifying horizontal tabs module. Unfortunately, there is no stable or dev release.

Thank you, Martin

So, why do we need to be providing new libraries for tabs or htabs. Why, are we going to have the elements module provide the library? This is all built into drupal core.

I have been using field group, because it IS a very convenient, quick way to group and nest fields. The tabs and accordions are great, but there does need to be a way to provide a custom ID for the tabs, so that you can link to a specific tab.

I just wonder why are we going in this direction of replicating libraries that already exist?

Every horizontal and vertical tab is having an unique ID. They are added now to the url has as well and we did it so, that on page load or click event on a tab, it is not jumping to the anchor, just opening it by default: http://drupal.org/node/1747804#comment-6383540
I believe this issue should be fix with this commit.

Hi, I'm using the 7.x dev version (updated today to see this this would fix it) and I'm finding the undesired behavior when using the ID tag of a field group with the URL. It does open the requested fieldgroup but it does treat it like an anchor, instead of displaying the full page. I would LOVE to be able to use links to access horizontal tabs.

Thanks for a great module!

I'm still having this exact same problem with field_group 7.x-1.5.

Is see this code inside horizontal-tabs.js:

      ...
      var focusID = $(':hidden.horizontal-tabs-active-tab', this).val();
      ...

        ...
        if (this.id == focusID) {
          tab_focus = $(this);
        }
        ...

I found no documentation about this. I suppose I have to make a hidden input field with class .horizontal-tabs-active-tab and set the tab ID there. But I have two problems. First there are no IDs on the tabs and no way to set them through field UI. Secondly how am I supposed to insert the right ID to this field? Do I have to write some glue code to read the value from URL hash and insert it into the hidden field?

Sounds very hard. I'll attach some screenshots to clarify.

What am I missing? Can this be reopened?

Here's a patch for those who just want a quick hack to solve this.

Oops.. that won't work so well. :)

Here's a better one.

I had the same problem with 7.x-1.5 -- the JS refers to something that cannot be set.

Since I cannot reopen this issue, I opened another one: https://www.drupal.org/node/2884058

For anybody who may need help with this issue, I was able to get this to work by adding IDs in the code. Maybe this can also be done using various hooks that are provided by field_group, but this here did the trick for me. In form_alter, I added this, which sets the IDs for the tabs:

$form['#groups']['group_step-zero']->format_settings['instance_settings']['id']  = 'group-step-zero';
$form['#groups']['group_step_one']->format_settings['instance_settings']['id']   = 'group-step-one';
$form['#groups']['group_step_two']->format_settings['instance_settings']['id']   = 'group-step-two';
...

When I then set the current ID using the trick with the #hidden field, the form correcly displayed:

$form['active_horizontal_tab'] = array(
    '#attributes' => array('class' => 'horizontal-tabs-active-tab'),
    '#type'       => 'hidden',
    '#value'      => ' ... one of the ids form the above list ...'
  );

Reroll of the hacky patch for 7.x.-1.6.
