public function CodeSnippet::settingsForm in CKEditor CodeSnippet 8

Returns a settings form to configure this CKEditor plugin.

If the plugin's behavior depends on extensive options and/or external data, then the implementing module can choose to provide a separate, global configuration page rather than per-text-editor settings. In that case, this form should provide a link to the separate settings page.

Parameters

array $form: An empty form array to be populated with a configuration form, if any.

\Drupal\Core\Form\FormStateInterface $form_state: The state of the entire filter administration form.

\Drupal\editor\Entity\Editor $editor: A configured text editor object.

Return value

array A render array for the settings form.
