How to set a menu item label as switch constant?

Hi,

I am trying to get a selected menu item label in switch condition.

Ex: menu has sub menu list as A,B,C,D,E,F. I have used callbacks to display menu in simulink model pane. Now I want to call them and make run some lines of code after comparing the switch.

Ex: I want the condition as below

selcected_label = ********;(what syntax should I use to get one of the label names selected or clicked ) switch (selected_label) case 'A' ----- ---- ----- case 'B' : : : case 'F' end;
