Rich pick list tab order

I am using rich:picklist. It has to two list boxes as it has and four buttons in between for moving one or all . I need to give tab order to this pi开发者_StackOverflowcklist together with buttons and boxes. Can anyone help?

I think you can't beacause there isn't tab index on the component.

Looking on the generated html source, boxes are tables and buttons are div : hard to define a tab order without the generated ids on such components...
