3rd level sidebar menu?

Hello!

I insert a 2 level categories list menu in the sidebar.
There is any possibility to make this menu 3 level category list?

Thank you

Hi,
in theory, yes, but I do not recommend - even now navigating at current menu is difficult.

Less menu items may help better then too many.

Thank you for your answer.

I know that the main menu have too much items, but it's not my choice...
I need a 3rd level for sidebar menu

Thanks
