new rendering of cumulative filter

[arboc]

new feature / enhancement of the cumulative filter:

• Display the categories and subcategories in a hierarchical way.
• Add a checkbox in front of each entry

(un-) select the checkboxes changes the filter.

example:

this maybe another solution for #173

I am in favor of this :). I already implemented this in one project, sort of:

// src/FrontendModule/CumulativeFilterModule.php
namespace App\FrontendModule;

use Contao\CoreBundle\Exception\RedirectResponseException;

class CumulativeFilterModule extends \Codefog\NewsCategoriesBundle\FrontendModule\CumulativeFilterModule
{
    protected function compile(): void
    {
        parent::compile();

        $inactiveCategories = $this->getInactiveCategories();

        $ids = [];

        if (null !== $this->activeCategories) {
            $ids = $this->activeCategories->fetchEach('id');
        }

        if (null !== $inactiveCategories) {
            $ids = array_merge($ids, $inactiveCategories->fetchEach('id'));
        }

        $this->Template->categories = $this->renderNewsCategories((int) $this->news_categoriesRoot, \array_unique($ids));
    }

    protected function getActiveCategories(array $customCategories = [])
    {
        try {
            return parent::getActiveCategories($customCategories);
        } catch (RedirectResponseException $e) {
            return null;
        }
    }
}

<!-- templates/mod_newscategories_cumulative.html5 -->
<?php $this->extend('block_unsearchable'); ?>

<?php $this->block('content'); ?>

  <?= $this->categories ?>

<?php $this->endblock(); ?>
