2 line menu navegation

i want to put a 2 line menu on my website https://paddingtonnews.co.uk/ but i been struggling.

i have found this https://stylizedweb.com/2010/08/16/use-the-link-description-in-wordpress-3-0-menus/ on internet and when i try to put just doesn’t work i have notice that was put up more than a year ago an it was for WP 3.0

can some one give me some lights in if it still works is just me doing something wrong or what changes i need to do to make it work for WP 4.0 ??

thanks in advance.
