update list/menu value dynamically
I need to update the content of a list/menu with values derived from a database..., the database query is initiated from a previous list/menu, which in turn is populated from a list/menu rewrite. In other words, I have 3 menus...first menu derives list from database, and it is independent query and i could do it,...but the second menu derives value from database as well but is dependent to selected value of first list,and 3rd list depends on second ones value. All 3 menus are contained within the same form. Am I asking the impossible? If anyone can help to achieve this, I would appreciate it.
