How to add tabbar in layout,place it to the layout left

I want a tabbar object placed on the left of a layout component. the layout componentis not the HTML elment .
For example
var layout = new dhtmlXLayoutObject(document.body,“1C”);
//var tabbar = layout.items[0].attachTabbar();
var tabbar = new dhtmlXTabBar(layout.items[0], “left”); //wrong;
How to do it.

In this case you need to use 2U layout pattern and attach tabbar in a cell “a”.
