Required library edition:
Required library file: dhtmlxcontainer.js

detaches object from cell (object moved to document.body, also style “display:none;” automatically added).

Create object

    <div id="myObj"> </div>

Init Layout, attach object to cell “a”

    var dhxLayout = new dhtmlXLayoutObject(document.body, "3L");
    dhxLayout.cells("a").attachObject("myObj");

Detach object

    dhxLayout.cells("a").detachObject();
    // object attached to document.body now
    // attach to another cell
    dhxLayout.cells("b").attachObject("myObj");

This approach can also be used for accordion, tabbar and windows items.
