Please help with the following:
I need a new widget (just a slightly altered select) that can be setup from the UI by anyone. I have done the following:
-
Created a new custom module and enabled it.
-
Created a new widget.
<?php namespace Drupalfiltered_selectPluginFieldFieldWidget; use DrupalCoreFieldFieldItemListInterface; use DrupalCoreFieldPluginFieldFieldWidgetOptionsSelectWidget; use DrupalCoreFormFormStateInterface; /** * Plugin implementation of the 'filtered_select' widget. * * @FieldWidget( * id = "filtered_select", * label = @Translation("Filtered Select"), * field_types = { * "entity_reference" * }, * multiple_values = FALSE * ) */ class FilteredSelectWidget extends OptionsSelectWidget { /** * {@inheritdoc} */ public function formElement(FieldItemListInterface $items, $delta, array $element, array &$form, FormStateInterface $form_state) { $element = parent::formElement($items, $delta, $element, $form, $form_state); // Use the parent select functionality, // just switch the element. $element['#type'] = 'fselect'; return $element; } } - Created new element so I can switch the theme. (not sure if this is necessary)
<?php namespace Drupalfiltered_selectElement; use DrupalCoreRenderElementSelect; /** * Provides the filtered select element. * * @FormElement("fselect") */ class FilteredSelect extends Select { /** * {@inheritdoc} */ public function getInfo() { $info = parent::getInfo(); // Theme switch. $info['#theme'] = 'fselect'; return $info; } } - It did not work otherwise so I also got a hook_theme up in my module file like this:
/** * Implements hook_theme(). */ function filtered_select_theme($existing, $type, $theme, $path): array { return [ 'fselect' => [ 'render element' => 'element', 'template' => 'fselect', ], ]; } - I just copied the template from core into my custom module and it works in the sense that it prints the right template, I have not yet altered this one, I just want to get the same old core functionality working under another name first.
Issue: My new render element seems to be missing the options array and I can’t figure out why. I’ve done really basic overwrites and I cannot understand why it does not build the options array.
Twig Var Dumps:

Please advise.
