About Trees Created as Shared Components

Previous releases of Oracle Application Express supported the creation of trees as Shared Components. Although existing trees are still supported, Oracle Application Express no longer supports the creation of trees as Shared Components.

Oracle Application Express now supports the generation of a jsTree tree region. jsTree is a JavaScript based, cross browser tree component. It is packaged as a jQuery plug-in. To learn more, see "Creating Trees".
