In this tutorial, I’ll show you how to add a “Read More” and “Show Less” button to your WooCommerce product description. This feature is especially useful for products with long descriptions, helping to keep the product page clean and user-friendly.

✅ Why Use a “Read More” Button?

Improve UX: Let users decide whether they want to see the full product description.
Optimize Layout: Keeps the page neat and focused by reducing visual clutter.
Faster Load Time: Minimizes initial content height, which speeds up page rendering.
Increase Engagement: Adds interactivity and encourages users to explore more product details.

🛠️ How to Implement

Below is the full code to add the “Read More” and “Show Less” functionality to your WooCommerce product description.

<?php
add_action('wp_footer', 'wat_product_description_expand_feature');
function wat_product_description_expand_feature() {
    if (!is_product()) return;
    ?>
    <style>
        .single-product div#tab-description {
            position: relative;
            overflow: hidden;
            padding-bottom: 30px;
        }

        .wat-description-collapsed {
            max-height: 800px;
            overflow: hidden;
            position: relative;
        }

        .single-product .tab-panels div#tab-description.panel:not(.active) {
            height: 0 !important;
        }

        .wat-description-toggle-button {
            text-align: center;
            cursor: pointer;
            position: absolute;
            bottom: 0;
            left: 0;
            right: 0;
            z-index: 999;
            background-color: #fff;
        }

        .wat-read-more-button:before {
            content: "";
            height: 60px;
            margin-top: -50px;
            display: block;
            background: linear-gradient(to bottom, rgba(255,255,255,0), rgba(255,255,255,1));
        }

        .wat-description-toggle-button a {
            color: #0057b8;
            display: block;
            padding: 5px 0;
            font-weight: 500;
        }

        .wat-description-toggle-button a:after {
            content: '';
            display: inline-block;
            width: 0;
            height: 0;
            margin-left: 8px;
            vertical-align: middle;
            border-left: 5px solid transparent;
            border-right: 5px solid transparent;
        }

        .wat-read-more-button a:after {
            border-top: 5px solid #0057b8;
        }

        .wat-read-less-button a:after {
            border-bottom: 5px solid #0057b8;
        }

        .wat-read-less-button:before {
            display: none;
        }
    </style>

    <script>
        (function($) {
            $(document).ready(function() {
                var $description = $('.single-product div#tab-description');

                if ($description.length > 0) {
                    var actualHeight = $description.outerHeight();
                    var maxHeight = 800;

                    if (actualHeight > maxHeight) {
                        $description.addClass('wat-description-collapsed');

                        var $readMoreBtn = $('<div class="wat-description-toggle-button wat-read-more-button"><a href="javascript:void(0);">Read More</a></div>');
                        $description.append($readMoreBtn);

                        var $readLessBtn = $('<div class="wat-description-toggle-button wat-read-less-button" style="display: none;"><a href="javascript:void(0);">Show Less</a></div>');
                        $description.append($readLessBtn);

                        $readMoreBtn.on('click', function() {
                            $description.removeClass('wat-description-collapsed');
                            $readMoreBtn.hide();
                            $readLessBtn.show();
                        });

                        $readLessBtn.on('click', function() {
                            $description.addClass('wat-description-collapsed');
                            $readLessBtn.hide();
                            $readMoreBtn.show();
                            $('html, body').animate({
                                scrollTop: $description.offset().top - 100
                            }, 300);
                        });
                    }
                }
            });
        })(jQuery);
    </script>
    <?php
}
?>

📋 How to Use

Paste into functions.php
Add the code above to your child theme’s functions.php file.
Customize the Max Height
The line var maxHeight = 800; sets the max height in pixels before showing the “Read More” button. Adjust this to suit your layout.
Customize Colors
Change the color #0057b8 in the CSS to match your theme.
Edit Button Text
Update the button labels:

var $readMoreBtn = $('<div class="wat-description-toggle-button wat-read-more-button"><a href="javascript:void(0);">Read More</a></div>');
var $readLessBtn = $('<div class="wat-description-toggle-button wat-read-less-button" style="display: none;"><a href="javascript:void(0);">Show Less</a></div>');

🌟 Highlighted Features

Auto Detection: The script only activates when the description exceeds the height threshold.
Fade Effect: Adds a gradient fade at the bottom for a smooth visual cue.
Auto Scroll: When collapsing, the page scrolls back to the top of the description.
Efficient: Runs only on single product pages, so it doesn’t affect performance site-wide.
