How to move the elem in javascript

Question

I know Javascript in the beginning level and I need some help.

left = '-180px';
$sub_menu.show().animate({'left' : left}, 200);

I want to move $sub_menu from the right side to 180pxfrom his default position before animate it, i.e. to make the indent on the right.

!!! EDIT !!!

Here my jsfiddle

For each menu element, on mouseenter, I enlarge the image, and show both sdt_active span and sdt_wrap span. If the element has a sub menu (sdt_box), then I slide it - if the element is the last one in the menu I slide it to the left, otherwise to the right. My problem is the last Menu 6. It must work as other menus only it should slide to the left on the same width.
