[Resolved] Dynamically list child categories in a widget

[Leonardo]

Hello!

I need something seemingly simple, but I’m not able to accomplish.

I want to dynamically list child categories in a widget depending on the selected parent category page.

Ex: I have a parent category called “Cameras” and within that category, there are subcategories. When opening the “Cameras” category page, I want this widget to show its child categories.

It’s possible?

Thanks!

Hi there,

you could create your own shortcode function with this PHP Snippet:

function list_subcategories_shortcode() {
    $categories = get_categories( array(
        'child_of' => get_queried_object_id(),
        'hide_empty' => false
    ) );
    if ( ! empty( $categories ) ) {
        $output = '<ul class="subcategory-list">';
        foreach ( $categories as $category ) {
            $output .= '<li><a href="' . get_category_link( $category->term_id ) . '">' . $category->name . '</a></li>';
        }
        $output .= '</ul>';
        return $output;
    }
    return '';
}
add_shortcode( 'list_subcategories', 'list_subcategories_shortcode' );

Then use a Block Element to add your [list_subcategories] shortcode to your archive pages.
It would need some to style.

Let me know.
