A method, apparatus, system, and signal-bearing medium that, in an embodiment, create concrete configuration associated with a page based on an abstract personal configuration. Wrapper code is also created, and the wrapper code, the page, and the concrete configuration are sent to a client. When executed at the client, the wrapper code manipulates portlets associated with the page using the concrete code. The personal configuration allows portlets to be arranged and managed dynamically on a per-user basis. The wrapper code causes the portlets to be dragged, dropped, resized, overlapped, and hidden.
