Date List element title display options not applying.

Version Information
Drupal Core 10.4.0
Webform: 6.2.9
Theme: Olivero; Bootstrap5

This is a regression triggered via Drupal core.

Notice that although the title option is set to "Invisible", same does not apply to the "Date part" options selected

@see 🐛 Date list labels are not visible above select field creating bad UX Fixed

Drupal Core 10.3, Webform 6.2.9, Theme Claro 10.4

Date List - repeats title/label for each Date Part.

Appears to have changed after installing Gavias Edmix 3.0.1 even though Claro theme is selected

Example of unnecessary labels

Can they be removed?

The select labels could be removed with a custom hook. Someone would have to write and share the code snippet.

jrockowitz → changed the visibility of the branch 3495192-date-list-part-title-display to hidden.

I created a POC MR to allows the date part title display to be customized.

Hi,
I've applied the MR!581 successfully for drupal core 10.3 and it is working as expected.

Steps I followed for testing:

• Add "Date list" element to a webform
• Select all Date part options, or your preferred options
• Set "Title display to "Invisible"
• Save and View
• After applying I can see the new field named "Date part title display" set it to invisible and it is working as expected

Attaching Screenshots for reference
Status - PASS

Here is quick fix for people wanting to revert back to the having the datelist title invisible.

/**
 * Implements hook_webform_element_alter())
 */
function MYMODULE_webform_element_alter(array &$element, \Drupal\Core\Form\FormStateInterface $form_state, array $context) {
  if (isset($element['#type']) && $element['#type'] === 'datelist') {
    $element['#after_build'][] = 'MYMODULE_webform_element_datelist_after_build';
  }
}

function MYMODULE_webform_element_datelist_after_build(array $element, FormStateInterface $form_state) {
  foreach (Element::children($element) as $child_key) {
    if (!isset($element[$child_key]['#title_display'])) {
      $element[$child_key]['#title_display'] = 'invisible';
    }
  }
  return $element;
}
