I am creating a VF page with standard controller and on that we need to have 12 picklist fields in one page-block and 12 dependent picklist fiields are dependent on other pick list values. i am getting Visualforce pages may not display more than 10 dependent picklists together with their controlling fields error. Is it possible to display all this fields in one page with validations?
