Question

  public function buildForm(array $form, FormStateInterface $form_state) {
          $form = parent::buildForm($form, $form_state);
          $config = $this->config('category_dynamic_block.settings');

          $form['section_title'] = array(
            '#type' => 'textfield',
            '#title' => $this->t('Section Title'),
            '#description' => $this->t('Enter a Section Title'),
          );

          $form['term_name'] = array(
            '#type' => 'entity_autocomplete',
            '#target_type' => 'taxonomy_term',
            '#selection_settings' => [
                 'target_bundles' => array('categories'),
            ],
            '#title' => $this->t('Term Name'),
              '#description' => $this->t('Enter a Category Vocab Term Name'),
          );

          $form['page_title'] = array(
            '#type' => 'entity_autocomplete',
            '#target_type' => 'node',
            '#selection_settings' => [
                'target_bundles' => array('article'),
            ],
            '#title' => $this->t('Page Title (' . $i . ')'),
            '#description' => $this->t('Enter Page Title to be displayed'),
          );

          return $form;}

我正在创建一个配置表单，我试图找出drupal 8中是否有一种方法允许用户为$ form ['page_title']字段输入多个值。

这个问题（带有表单api的无限制文本字段）可能就是您要找的内容：https://drupal.stackexchange.com/questions/208012/unlimited-textfields-with-form-api

基本上你需要添加一些ajax：

<table>
  <tbody>
    <tr>
      <td>
        <div class="hover">Hover me</div>
      </td>
    </tr>
    <tr>
      <td>
        <div class="hover">Hover me</div>
      </td>
    </tr>
    <tr>
      <td>
        <div class="hover">Hover me</div>
      </td>
    </tr>
   </tbody>
</table>

如何创建一个实体引用字段，允许配置表单中的无限值？
