Validation-failing fields that are not in the current vertical tab block submit but produce zero feedback

Thu, Sep 12, 2019

Fields that are not in the current vertical tab when Submit is pressed and that fail validation cause submission to silently fail: Nothing happens, no feedback to the service provider at all

Searched for:

• drupal 8 vertical tabs javascript validation
• silent fails with HTML5 or JS validation when required or otherwise problematic field is on a ‘closed’ vertical tab

There’s this lonely core issue with patch: Correct vertical tab does not focus on form validation [#2911932] | Drupal.org

It seems to be accepted as a Field Group issue though: Ensure visibility of invalid fields (JS)

Some think this is fixed? Highlight vertical tabs when they have elements with errors [#607752] | Drupal.org

Going to try to work around it with https://www.drupal.org/project/clientside_validation
