Magento 2 remove category filter from list page filters?

Question

How can I remove Category Filter from Magento 2 Product List Page.

Answer 1

You have to override core file into your theme, Category layered navigation comes form core file,

vendor/magento/module-layered-navigation/view/frontend/templates/layer/view.phtml

You have to get files from core and keep in your theme,

app/design/frontend/{Vendor}}/{themename}}/Magento_LayeredNavigation/templates/layer/view.phtml

Now you can set condition for this,

<?php  if($filter->getName() != __('Category')) { } ?>

in code.

<?php

/**
 * Category layered navigation
 *
 * @var $block \Magento\LayeredNavigation\Block\Navigation
 */
?>
<?php if ($block->canShowBlock()): ?>
    <div class="block filter">
        <div class="block-title filter-title">
            <strong><?php /* @escapeNotVerified */ echo __('Shop By') ?></strong>
        </div>

        <div class="block-content filter-content">
            <?php echo $block->getChildHtml('state') ?>

            <?php if ($block->getLayer()->getState()->getFilters()): ?>
                <div class="block-actions filter-actions">
                    <a href="<?php /* @escapeNotVerified */ echo $block->getClearUrl() ?>" class="action clear filter-clear"><span><?php /* @escapeNotVerified */ echo __('Clear All') ?></span></a>
                </div>
            <?php endif; ?>
            <?php $wrapOptions = false; ?>
            <?php foreach ($block->getFilters() as $filter): ?>
                <?php if (!$wrapOptions): ?>
                    <strong role="heading" aria-level="2" class="block-subtitle filter-subtitle"><?php /* @escapeNotVerified */ echo __('Shopping Options') ?></strong>
                    <dl class="filter-options" id="narrow-by-list">
                <?php $wrapOptions = true; endif; ?>
                <?php  if($filter->getName() != __('Category')) { ?>
                    <?php if ($filter->getItemsCount()): ?>
                        <dt role="heading" aria-level="3" class="filter-options-title"><?php echo $block->escapeHtml(__($filter->getName())) ?></dt>
                        <dd class="filter-options-content"><?php /* @escapeNotVerified */ echo $block->getChildBlock('renderer')->render($filter); ?></dd>
                    <?php endif; ?>
                    <?php } ?>
            <?php endforeach; ?>
            <?php if ($wrapOptions): ?>
                </dl>
            <?php endif; ?>
        </div>
    </div>
<?php endif; ?>

Better to use as:

<?php  
if($filter->getRequestVar() != 'cat') { 
    // ...
} 
?>

Answer 3

Since this is the top result in Google for my search "magento 2 remove category filter from layered navigation", and all the answers suggest entirely replacing a template file (which is subject to Theme-level discrepancies) I thought I'd provide an answer that does not involve a .phtml template replacement.

The Category filter can be removed from Layered Navigation "Shopping Options" list by using a Plugin.

In your module's etc/di.xml file, define the plugin and class DI properties:

    <type name="Magento\Catalog\Model\Layer\FilterList">
        <plugin name="remove_layered_nav_category_filter" type="Vendor\Module\Plugin\Catalog\Model\Layer\FilterList" sortOrder="1" disabled="false" />
    </type>

    <type name="Vendor\Module\Plugin\Catalog\Model\Layer\FilterList">
        <arguments>
            <argument name="categoryFilters" xsi:type="array">
                <item name="catalogsearch_category" xsi:type="string">Magento\CatalogSearch\Model\Layer\Filter\Category</item>
                <item name="category" xsi:type="string">Magento\Catalog\Model\Layer\Filter\Category</item>
            </argument>
        </arguments>
    </type>

And declare the Plugin class:

namespace Vendor\Module\Plugin\Catalog\Model\Layer;


class FilterList
{
    const CATALOG_CATEGORY_FILTER = 'category';
    const CATALOG_SEARCH_CATEGORY_FILTER = 'catalogsearch_category';

    /**
     * @var array
     */
    protected $categoryFilterTypes = [
        self::CATALOG_SEARCH_CATEGORY_FILTER => \Magento\CatalogSearch\Model\Layer\Filter\Category::class,
        self::CATALOG_CATEGORY_FILTER        => \Magento\Catalog\Model\Layer\Filter\Category::class
    ];

    /**
     * FilterList constructor.
     *
     * @param array $categoryFilters
     */
    public function __construct(array $categoryFilters)
    {
        $this->categoryFilterTypes = array_merge($this->categoryFilterTypes, $categoryFilters);
    }


    /**
     * Remove Category Filter from FilterList
     *
     * @param \Magento\Catalog\Model\Layer\FilterList $subject
     * @param                                         $result
     * @param \Magento\Catalog\Model\Layer            $layer
     * @return array
     */
    public function afterGetFilters(
        \Magento\Catalog\Model\Layer\FilterList $subject,
        $result,
        \Magento\Catalog\Model\Layer $layer
    ) {
        foreach ($result as $idx => $filter) {
            if ($this->isCategoryFilter($filter)) {
                unset($result[$idx]);
                break;
            }
        }

        return array_values($result);
    }

    /**
     * Determine if given Filter is one of the declared Category Filter types
     *
     * @param $filter
     * @return bool
     */
    private function isCategoryFilter($filter)
    {
        return \in_array(get_class($filter), $this->categoryFilterTypes);
    }
}

This leaves other Filters (e.g., Attribute, Price, Decimal) in place while removing any of the possible Category filters. Should additional Category filters be introduced, a simple change to DI configuration is all that is necessary to extend the functionality.

Remove Block

Answer 5

Sadly the fix from Rakesh is not working for me. The filter is not collapsible anymore. How can we still remove the categorie filter in our code? On default we have the filters collapsible.

<?php if ($block->canShowBlock()): ?>
<div class="block filter" id="layered-filter-block" data-mage-init='{"collapsible":{"openedState": "active", "collapsible": true, "active": false, "collateral": { "openedState": "filter-active", "element": "body" } }}'>
    <?php $filtered = count($block->getLayer()->getState()->getFilters()) ?>
    <div class="block-title filter-title" data-count="<?= /* @escapeNotVerified */ $filtered ?>">
        <strong data-role="title"><?= /* @escapeNotVerified */ __('Shop By') ?></strong>
    </div>
    <div class="block-content filter-content">
        <?= $block->getChildHtml('state') ?>

        <?php if ($block->getLayer()->getState()->getFilters()): ?>
            <div class="block-actions filter-actions">
                <a href="<?= /* @escapeNotVerified */ $block->getClearUrl() ?>" class="action clear filter-clear"><span><?= /* @escapeNotVerified */ __('Clear All') ?></span></a>
            </div>
        <?php endif; ?>
        <?php $wrapOptions = false; ?>
        <?php foreach ($block->getFilters() as $filter): ?>
            <?php if ($filter->getItemsCount()): ?>
                <?php if (!$wrapOptions): ?>
                    <strong role="heading" aria-level="2" class="block-subtitle filter-subtitle"><?= /* @escapeNotVerified */ __('Shopping Options') ?></strong>
                    <?php $range = implode(' ', range(0, $filter->getItemsCount())); ?>
                    <div class="filter-options" id="narrow-by-list" data-role="content" data-mage-init='{"accordion":{"openedState": "active", "collapsible": true, "active": "<?php echo $range; ?>", "multipleCollapsible": true}}'>
                <?php  $wrapOptions = true; endif; ?>
                <?php  if($filter->getName() != __('Category')) { } ?>
                <div data-role="collapsible" class="filter-options-item">
                    <div data-role="title" class="filter-options-title"><?= /* @escapeNotVerified */ __($filter->getName()) ?></div>
                    <div data-role="content" class="filter-options-content"><?= /* @escapeNotVerified */ $block->getChildBlock('renderer')->render($filter) ?></div>
                </div>
            <?php endif; ?>
        <?php endforeach; ?>
        <?php if ($wrapOptions): ?>
            </div>
        <?php else: ?>
            <script>
                require([
                    'jquery'
                ], function ($) {
                    $('#layered-filter-block').addClass('filter-no-options');
                });
            </script>
        <?php endif; ?>
    </div>
</div>
