How can the Webform element Form display defaults be set?

Question

Every webform element has a little section like this:

Where can one set these defaults, for Title display location, Description display location, and Help display location?

It does not appear to be in any of the webform overall settings or webform specific settings.

If it's the default for the element type, is there a programmatic way to override the default (but not if set for an individual element)?

Doesn't matter much whether setting or overriding this default on a sitewide or webform-specific level, just want the ability to switch Title display from "Inline" to "Before" for all the elements on a form, as design requests change, without having to edit all individually.

Answer 1

It looks default title display is set in Drupal core:

https://git.drupalcode.org/project/drupal/-/blob/9.5.x/core/lib/Drupal/Core/Form/FormBuilder.php#L923-930

Answer 2

Per Webform maintainer Jacob Rockowitz:

In your theme or module you can create a hook_preprocess_form_element() which overrides the default #title_display set via template_preprocess_form_element().

@see template_preprocess_form_element().

Or:

Maybe you can use hook_webform_element_alter() to set the #title_display before template_preprocess_form_element() sets it.

I specifically avoided implementing a customizable default #title_display and #description_display because some themes have different default #title_display.

From How to set the default Title position for an element? (Issue #3003067 on Drupal.org)

So as ognockocaten suggests, 'default' means 'the default of Drupal' (or the theme if it alters this), not a default set in Webform.

Also, in my experience, Webform has minimal CSS to get this to work and is likely to fail depending on your theme's CSS, you may need to add styles in your theme for the classes webform-element--title-inline > .label and webform-element--title-inline > .control to ensure that the Inline option does indeed put the label and the input inline, for example.
