Oracle Application Home Page navigator 12.1.3

Hi,

We are using R12.1.3. Currently, all our responsibilities shows menus and functions in a tree view. But, we wanted like 11i instance navigator.

Responsibility to be shown on the left side and all its menus and functions to be shown on the right side of the region.

To achieve that, I have set some profile options FND: Disable Configurable Home Page: True.

The requirement is, if I have only one responsibility "Employee Self Service", all its menus and functions are not showing on the right side by default without clicking on the responsibility. If I have more than one responsibility, we expect the first responsibility's menus and functions to be shown by default without click on the responsibility. How can we achieve this?
