Add category

Hi there,

It looks like your parent and child categories are already set up correctly. What you need is to automatically show a list of subcategories on the parent category archive page.

GP and GB don’t have a built-in option for this, so it will require some custom code. You can use this shortcode to output subcategories of the current parent:

function subcategory_list_shortcode($atts) {
    $atts = shortcode_atts(array(
        'parent' => false,
    ), $atts);

    $parent_id = $atts['parent'];

    if (!$parent_id) {
        $parent_cat = get_queried_object();
        $parent_id = $parent_cat->term_id;
    }

    $args = array(
        'taxonomy' => 'category',
        'child_of' => $parent_id,
    );

    $subcategories = get_terms($args);

    if (empty($subcategories)) {
        return;
    }

    $output = '<ul class="subcategory-list">';
    foreach ($subcategories as $subcategory) {
        $term_link = get_term_link($subcategory);
        $output .= '<li><a href="' . esc_url($term_link) . '">' . esc_html($subcategory->name) . '</a></li>';
    }
    $output .= '</ul>';

    return $output;
}
add_shortcode('subcategory_list', 'subcategory_list_shortcode');

As your archive pages are already using a GP Block Element Page Hero, you can add the [subcategory_list] shortcode directly inside that Block Element. Remember to enable Execute Shortcodes in the settings.

The output may need some CSS for styling, depending on how you want the subcategories to look.

You’re very welcome!
