Add option to choose if 'hx-push-url' should be 'true' in the HTMX View's exposed form and pager

>>> [!note] Migrated issue   Reported by: [sandeshyadav](https://www.drupal.org/user/1982324) Related to !38 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> Currently, in the view's HTMX display, the exposed form does not update URLs to the browser. While this is the expected behaviour and fine for some cases, sometimes we need the URLs in the browser, based on the selected filters, so that we can share and bookmark the links accordingly. In Drupal's standard AJAX enabled view, this can be achieved either through Custom JS code or through <a href="https://www.drupal.org/project/views_ajax_history">Views AJAX History</a> module. But in HTMX views, we won't need extra JS code or module to achieve the same because HTMX already has <code>hx-push-url</code> attribute. We just have to set <code>hx-push-url</code> to <code>true</code> and HTMX takes care of URL updates, history and browser navigation. <h3 id="summary-proposed-resolution">Proposed resolution</h3> Step 1 We will add a checkbox to set <code>push_url</code> option in the view's UI: Advanced > Exposed form section. This will decide if the user wants to update URLs through the exposed form or not. <img src="https://www.drupal.org/files/issues/2025-08-10/Screenshot_20250810_140810.png" alt="Views HTMX Display Exposed Form"> <img src="https://www.drupal.org/files/issues/2025-08-10/Screenshot_20250810_171205.png" alt="Views HTMX Display Exposed Form"> Here is the code to achieve this. In <code>src/Plugin/views/display/Htmx.php</code>, <pre>  protected function defineOptions() {     $options = parent::defineOptions();     $options['push_url'] = ['default' => FALSE];     return $options;   }   public function optionsSummary(&$categories, &$options) {     parent::optionsSummary($categories, $options);     $options['push_url'] = [       'category' => 'exposed',       'title' => $this->t('Push Url'),       'value' => $this->getOption('push_url') ? $this->t('Yes') : $this->t('No'),       'desc' => $this->t('Change whether or not the exposed filters will push urls to browser\'s address bar.'),     ];   }   public function buildOptionsForm(&$form, FormStateInterface $form_state) {     parent::buildOptionsForm($form, $form_state);     $section = $form_state->get('section');     if ($section == 'push_url') {       $form['#title'] .= $this->t('Push Url');       $form['push_url'] = [         '#description' => $this->t('The Urls will be updated in the address bar'),         '#type' => 'checkbox',         '#title' => $this->t('Push Url'),         '#default_value' => $this->getOption('push_url') ? 1 : 0,       ];     }   }   public function submitOptionsForm(&$form, FormStateInterface $form_state) {     parent::submitOptionsForm($form, $form_state);     $section = $form_state->get('section');     if ($form_state->getValue('push_url')) {       $this->setOption('push_url', (bool) $form_state->getValue('push_url'));     }     else {       unset($this->options['push_url']);       unset($this->display['display_options']['push_url']);     }   }</pre>Step 2 We already have <code>htmx_form_views_exposed_form_alter()</code>, where we can modify the code to adjust the <code>hx-push-url</code> attribute through <code>pushUrl()</code>. <pre>function htmx_form_views_exposed_form_alter(&$form, FormStateInterface $form_state, $form_id): void {   // .....   //Fetches the value of push_url. Can be TRUE or FALSE.   $pushUrl = $view->getDisplay()->options['push_url'];   // .....   // Sets hx-push-url to true or false based on $pushUrl value.   $htmx->pushUrl($pushUrl) }</pre><h3 id="summary-data-model-changes">Data model changes</h3> Not really any change in data model. Just adds an extra option in views display.
