Have you ever thought what will you do as developer when you will need to change the product toolbar limiter dropdown into the links?

Well, here I’m going to guide you about it. All you need to do is to replace below code,

<select id="limiter" data-role="limiter" class="limiter-options">
            <?php foreach ($block->getAvailableLimit() as $_key => $_limit): ?>
                <option value="<?php /* @escapeNotVerified */ echo $_key ?>"<?php if ($block->isLimitCurrent($_key)): ?>
                    selected="selected"<?php endif ?>>
                    <?php /* @escapeNotVerified */ echo $_limit ?>
                </option>
            <?php endforeach; ?>
 </select>

With:

<?php foreach ($block->getAvailableLimit() as $_key => $_limit): ?>
        <a data-role="limiter" href="#" data-value="<?php /* @escapeNotVerified */ echo $_key ?>"<?php if ($block->isLimitCurrent($_key)): ?>
            class="selected"<?php endif ?>>
            <?php /* @escapeNotVerified */ echo $_limit ?>
        </a>
<?php endforeach; ?>

You need to do replacement in this file -> Magento_Catalog/templates/product/list/toolbar/limiter.phtml

Well, once you’re clear with the code replacement, you will able to see toolbar limiter like: 9 | 15 | 30 | All as links.
