I am just wandering is it possible to have a menu bar (in header) on left and right.
I need 'cart' to appear on the right end of it.

I am not quite clear what you are asking. %pages puts the menu on the left and %page-right puts it on the right. To have a cart appear will mean determining the selector for the cart and using CSS to reposition it.

Thanks for answering

Cart is just a regular WP page, my Q is - may I have two menus, one in the left side and one in the right side and how to do that?

the answer is no and yes and it depends.
NO - not a built in theme feature
YES - anything is 'possible'
Depends - on how much work/time you want to spend on it.

Atahualpa has two menus - a page and a category menu. Atahualpa provides you with a link to the wordpress menus, so you could use one wordpress menu and associate it with the %pages, and the second with %cat (%pages and %cat are the menu place holders in the 'configure header area' option for the menus

You could use %cat-right to cause the one menu with 'cart' to display to the right. Now with CSS Inserts, you could make it's menu background transparent and move it's position up so it overlaps the %pages' menu.

let us know how it works out.

It worked!
Thanks gazillion times
