The following steps describe how to add, remove, and arrange portlets within a layout.
When you add a portlet to a layout, the layout is refreshed, and its existing portlets return to their initial states. For example, if you had been working in a Custom Query portlet, you will need to re-execute the Custom Query to retrieve the results you were working on before you added the new portlet.
Unless you have the Group Layout Configuration privilege, you cannot re-order portlets in group layouts. If you do have the Group Layout Configuration privilege, remember that your changes affect all users who have access to the layout.
