Portal layout offers users the freedom to personalize and outline how a set of selected portlets should appear on a page. Users can perform operations such as drag and drop, collapse and expand, minimize and maximize on each portlet.

Updated: Auto save portlet position into session. For more technology details, please refer to our Component Reference - PortalLayout
