How to limit joomla 1.5 main menu into 2 levels?

i have this menu structure: Products->Shoes->Men. i have this kind of menu structure because i have a specific module to be shown in the Men section only. my problem is how can i limit the rendering of my main menu only up to Shoes(that is开发者_开发技巧 up to Products->Shoes only). i hope i get the right question for you guys. thanks for any help.

In the admin area go to Modules

Find your Menu and in the parameters you have the option to change how many levels get rendered
