As I had the same issue here an example code to add available categories in a checkbox list

In yourtheme/functions.php add following code lines:

add_filter('listo_list_types', 'listo_list_types_func');
function listo_list_types_func($list_types){
	$list_types['categories'] = 'Listo_Categories';
	return $list_types;
}

class Listo_Categories implements Listo {

	public static function items(){
		$categories = get_categories(['hide_empty' => 0]);

		foreach( $categories as $cat ){
			$items [$cat->cat_ID] = $cat->name;
		}

		return $items;
	}

	public static function groups(){}
}

In your CF7 form add the following [shortcode]

[checkbox categories data:categories]

That’s it

Hope this help
