Solution
We used the drop-down menu so that the user can access all products in one click without leaving the home page. The user is a rather young person, actively using great technology and the pages he visits are modern, so this solution, although non-standard, is not a problem in terms of habits and knowledge of the user.
The user also has easy access from the main menu to the shopping cart (and the option to immediately remove products without moving to another page) and to his or her account (login, logout, details and settings).
