I need to create new urls with the current category slug name

Hello!

I need a code to paste in the widget that works like this:

For example we are in the page http://domain.com/paris/france/

“/paris/” is the slug name of the current page category and “/france/” is the parent category of “/paris/”

I need to show the next list:

1. Cars in Paris, France, linked to http://domain.com/cars-in-paris-france/
2. Bueses in Paris, France, linked to http://domain.com/buses-in-paris-france/
3. Trains in Paris, France, linked to http://domain.com/trains-in-paris-france/

Thanks
