Theming Views in Drupal 8 – Custom Style Plugins
Views is in Drupal 8 core. We all know that by now. Twig is the new templating engine in Drupal 8. This we also know. But do we know how to interact programmatically with the first in order to theme a View using the second? Aside from overriding View templates like with any other subsystem, we have available a more powerful alternative in the form of Views plugins (Display, Style, Row and Field).
In this article, we are going to look at how we can create a custom Style plugin for Views in Drupal 8. We will use the Bootstrap tab markup as a goal and implement a tabbed output for our View results. In the View configuration, the Style settings will allow us to specify which field will be used as the tab navigation copy, leaving the rest of the fields shown in the respective tab panes. Basically, each View result will represent a tab - so this example is not suited for Views which have more than a few results. The main goal is to illustrate how we can create our own Views Style plugins in Drupal 8.
We will not cover the details on how you can use Bootstrap in your project. However, you can check out the documentation page on assets or even this article on how to make sure anonymous users can benefit from jQuery being loaded on the page. And if you want to see the code we write ahead of time, you can find it in this repository within the Demo module.
What Is the Style Plugin?
The Views Style plugin is the one responsible for rendering the listing. Notable examples of core Style plugins are Unformatted List, HTML List, Table or Grid. They are used by the Display plugin and they in turn use Row plugins that represent one item in the listing.
In Drupal 8, all Views plugin types are built using the new Plugin system and share some common functionality (they always extend from the same Views PluginBase).
Let’s now create our own such Style plugin that can be used by most Display types (Page, Block, etc) and which uses the Field row plugin.
The Bootstrap Tabs Style Plugin
The first step is to create our plugin class located in the Plugin/views/style folder of our module:
namespace Drupal\demo\Plugin\views\style;
use Drupal\Core\Form\FormStateInterface;
use Drupal\views\Plugin\views\style\StylePluginBase;
/**
* A Views style that renders markup for Bootstrap tabs.
*
* @ingroup views_style_plugins
*
* @ViewsStyle(
* id = "bootstrap_tabs",
* title = @Translation("Bootstrap Tabs"),
* help = @Translation("Uses the Bootstrap Tabs component."),
* theme = "demo_bootstrap_tabs",
* display_types = {"normal"}
* )
*/
class BootstrapTabs extends StylePluginBase {
/**
* Does this Style plugin allow Row plugins?
*
* @var bool
*/
protected $usesRowPlugin = TRUE;
/**
* Does the Style plugin support grouping of rows?
*
* @var bool
*/
protected $usesGrouping = FALSE;
/**
* {@inheritdoc}
*/
protected function defineOptions() {
$options = parent::defineOptions();
$options['tab_nav_field'] = array('default' => '');
return $options;
}
/**
* {@inheritdoc}
*/
public function buildOptionsForm(&$form, FormStateInterface $form_state) {
parent::buildOptionsForm($form, $form_state);
$options = $this->displayHandler->getFieldLabels(TRUE);
$form['tab_nav_field'] = array(
'#title' => $this->t('The tab navigation field'),
'#description' => $this->t('Select the field that will be used as the tab navigation. The rest of the fields will show up in the tab content.'),
'#type' => 'select',
'#default_value' => $this->options['tab_nav_field'],
'#options' => $options,
);
}
}
