Problem/Motivation
I am using the webform_multiple element in a custom WebformElement that is a composite element. When I go to the translation page in to translate the form, only the element title is visible to translate. I've stepped through all the code which led me to the Drupal\webform\WebformTranslationConfigManager::buildConfigWebformFormDefaultPropertyElement() method that handles rendering the elements correctly on the add config translation form.
Here is an example of my custom element:
class CaseWizardOptions extends WebformElementBase {
/**
* {@inheritdoc}
*/
public function form(array $form, FormStateInterface $form_state): array {
$form = parent::form($form, $form_state);
$form['solutions'] = [
'#type' => 'fieldset',
'#title' => $this->t('Solutions'),
'#open' => TRUE,
];
$form['solutions']['solutions'] = [
'#type' => 'webform_multiple',
'#empty_items' => 0,
'#element' => [
'action' => [
'#type' => 'select',
'#title' => $this->t('Action'),
'#options' => [
'recommendation' => $this->t('Show recommendation in modal'),
'open_case' => $this->t('Open case'),
'link_account' => $this->t('Link account'),
'open_new_page' => $this->t('Open new page'),
],
],
'title' => [
'#type' => 'textfield',
'#title' => $this->t('Title'),
],
'description' => [
'#type' => 'text_format',
'#title' => $this->t('Description'),
'#allowed_formats' => ['full_html'],
],
'recommendation_label' => [
'#type' => 'textfield',
'#title' => $this->t('Recommendation label'),
'#description' => $this->t('Use for recommendation modal action.'),
],
'recommendation' => [
'#type' => 'text_format',
'#title' => $this->t('Recommendation'),
'#description' => $this->t('Use for recommendation modal action.'),
'#allowed_formats' => ['full_html'],
],
'recommendations_url' => [
'#type' => 'url',
'#title' => $this->t('Recommendations url'),
'#description' => $this->t('Use for recommendation modal action.'),
],
'new_page_url' => [
'#type' => 'url',
'#title' => $this->t('New page url'),
'#description' => $this->t('Use for open new page action.'),
],
],
'#weight' => 100,
];
return $form;
}
/**
* {@inheritdoc}
*/
public function getOffCanvasWidth(): string {
return WebformDialogHelper::DIALOG_WIDE;
}
/**
* {@inheritdoc}
*/
public function prepare(array &$element, ?WebformSubmissionInterface $webform_submission = NULL): void {
parent::prepare($element, $webform_submission);
foreach ($element['#solutions'] as $solution) {
$element['#options'][] = $solution;
}
$element['#attached']['library'][] = 'core/drupal.dialog.ajax';
}
/**
* {@inheritdoc}
*/
protected function defineDefaultProperties(): array {
$properties = parent::defineDefaultProperties();
$properties['solutions'] = [];
// Conditional logic.
$properties['states'] = [];
$properties['states_clear'] = TRUE;
// Wrapper.
$properties['wrapper_type'] = 'fieldset';
return $properties;
}
}
Steps to reproduce
Implement a custom webform element plugin with the example code I've provided above. Attempt to translate the webform and this element will only allow you to translate the element title.
