Magento 2: How is it possible to call a static block in category description?

Question

is it possible to call static blocks in the category description of magento 2?

I don ́t want to use the "Add CMS Block" DropDown under the description field.

It is necessary to call the blocks in the description field.

I would like to call blocks like sliders: {{revslider alias="fullslider-en"}}

or product lists:

{{block class="Infortis\Base\Block\Product\ProductList\Featured" template="product/list.phtml" category_id="13"}}

Any ideas?

Many thanks in advance Andi

Override View.php block

vendor/magento/module-catalog/Block/Category/View.php

Add class \Zend_Filter_Interface in your block to filter output to html

...
protected $templateProcess;
...
public function __construct(
 ...
 \Zend_Filter_Interface $templateProcess
 ...
) {
 ...
 $this->templateProcess = $templateProcess;
 ...
}
public function filterOutputHtml($string) 
{
 return $this->templateProcess->filter($string);
}

In your di.xml

app/code/Vendor/Module/etc/di.xml

<type name="Vendor\Module\Block\Category\View">
 <arguments>
 <argument name="templateProcessor" xsi:type="object">Magento\Widget\Model\Template\Filter</argument>
 </arguments>
</type>

Now call filterOutputHtml() to description.phtml

Override description.phtml to your theme

vendor/magento/module-catalog/view/frontend/templates/category/description.phtml

<?php 
//Get category description
$_description = $block->getCurrentCategory()->getDescription();
//Convert block {{ }} to html
<?php echo $block->filterOutputHtml($_description);

You need to override core functionality to show widget options then you can insert static block using widget interface.

Create/Edit your di.xml and define a preference:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <preference for='Magento\Catalog\Block\Adminhtml\Helper\Form\Wysiwyg\Content' type='[Vendor]\[Module]\Block\Adminhtml\Helper\Form\Wysiwyg\ContentRewrite'/>
</config>

File Magento\Catalog\Block\Adminhtml\Helper\Form\Wysiwyg\Content

protected function _prepareForm()
{
 /** @var \Magento\Framework\Data\Form $form */
 $form = $this->_formFactory->create(
 [
 'data' => ['id' => 'wysiwyg_edit_form', 'action' => $this->getData('action'), 'method' => 'post'],
 ]
 );
 $config['document_base_url'] = $this->getData('store_media_url');
 $config['store_id'] = $this->getData('store_id');
 $config['add_variables'] = false;
 $config['add_widgets'] = true; // change this from false to true
 $config['add_directives'] = true;
 $config['use_container'] = true;
 $config['container_class'] = 'hor-scroll';
 $form->addField(
 $this->getData('editor_element_id'),
 'editor',
 [
 'name' => 'content',
 'style' => 'width:725px;height:460px',
 'required' => true,
 'force_load' => true,
 'config' => $this->_wysiwygConfig->getConfig($config)
 ]
 );
 $this->setForm($form);
 return parent::_prepareForm();
}

You may also need to override the block and view file for templateProcess.
