Question

I would like to remove the categories section on the layered navigation but do not see where they are called within layered navigation module.

Answer 1

Copy the following file:

/vendor/magento/theme-frontend-luma/Magento_LayeredNavigation/templates/layer/view.phtml

to your theme:

app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/templates/layer/view.phtml

And put the Category condition like below:

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

// @codingStandardsIgnoreFile

?>
<?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><?= /* @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 $filter): ?>
                <?php if (!$wrapOptions): ?>
                    <strong role="heading" aria-level="2" class="block-subtitle filter-subtitle"><?= /* @escapeNotVerified */ __('Shopping Options') ?></strong>
                    <dl class="filter-options" id="narrow-by-list">
                <?php $wrapOptions = true; endif; ?>
                    <?php if ($filter->getItemsCount() && $filter->getName() != 'Category'): ?>
                        <dt role="heading" aria-level="3" class="filter-options-title"><?= $block->escapeHtml(__($filter->getName())) ?></dt>
                        <dd class="filter-options-content"><?= /* @escapeNotVerified */ $block->getChildBlock('renderer')->render($filter) ?></dd>
                    <?php endif; ?>
            <?php endforeach; ?>
            <?php if ($wrapOptions): ?>
                </dl>
            <?php endif; ?>
        </div>
    </div>
<?php endif; ?>

Use the above content for your view.phtml file.

Answer 2

Checked with M2.4.1. There is a configuration here Store -> Configuration -> Catalog -> Catalog

Answer 3

In Magento 2.3.4:

1. copy file vendor/magento/theme-frontend-luma/Magento_LayeredNavigation/templates/layer/view.phtml to /Magento_LayeredNavigation/templates/layer/view.phtml
2. Find <?php if ($filter->getItemsCount()) : ?>
3. Replace with <?php if ($filter->getItemsCount() && get_class($filter) != \Magento\CatalogSearch\Model\Layer\Filter\Category::class) : ?>

Answer 4

The layered navigation categories are called in one of the core files as below:

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

You need to override this file in your theme and then change the content of the file however you want.

Add below directory in your theme:

app/design/frontend/vendor_name/theme_name/Magento_LayeredNavigation/templates/layer

Then put above file view.phtml in this path.
