I am trying to develop a GUI involving two popup menus. In the first popup menu, there are 3 options. The number of options in the second popup menu should depend on the selected option in the first menu.
If the first option is selected in the first popup menu, there should be 4 options in the second popup menu. Similarly, if the second option is selected in the first popup menu, there should be 5 options in the second popup menu and so on.
Most importantly I have to provide separate formulae for each option from second popup menu.
How can I do this?
