How to change of "child content" of menu item?

Hello,
by default submenu items shows up aligned to left border of parent menu item.
Is it possible to change submenu position ?

I would like to align some submenus to right border.

This position is computed by the menu script so there is no easy way to achieve this effect without recode this script.

I changed position with CSS rule

.childcontent { left: -21px!important;}

Yes it is a solution but can cause problem is some template width and also when you other levels of menu.
