I created new form which extends from svy_nav_fr_p_openTabs. On open solution method I assign my form to global variable globals.nav.openLayoutFormName = “prg_nav_fr_p_openTabs”
I don’t overwrite any methods but when I run solution I don’t see any more multiple layout tabs. Every time when I call other form from menu I can see only one layout tab and previous one closed automatically.
I need to use my form to control some functions from framework. But when i try to use inheritance I loose some functionality .
Multiple tabs per progam is a property. You have to go to the configurator and set the property to true.
