Can items listed under Categories on menu?

[railroadguy]

I have found many mods but not one that when you click on a Category, not only will all the products show on the page, but a selectable list will then also appear under the Category heading in the menu.

 

In this way if I have 20 products people will not have to scroll down the whole page to see them but also have a list to select from.

 

Thanks for any pointers.
