Hi,

Currently I have 4 objects A,B,C and D these are the parent object for Object O.  So when I come from record A, on object O page layout i want to display only A's lookup field and hide rest 3  lookup fields B,C, D.

Similarly when I come from record B, on O's page layout I want to display B's lookup field and hide 3 rest lookup fields A,C, D.

And so on for remaining 2 objects..

I know this can be achieved through record type, but in my requirement they dont want to achieve it through standard record type so I want to use Visualforce page to avoid record type selection menu.

I have done some initial hands on but not getting up to the mark... please help!!!!

NOTE:I have replaced Fund, CDE, Allocatee and Project with A, B, C and D and program with O.

Hi

 I want to create a custom button in opportunity layout page, such that when I click the button, a section in opportunity should become hidden. When I click again it should appear again. Basically it should hide/unhide on successive clicks
