M2_STRLIST, ok the msg parameter and operation.
But he is in between of other elements, and I can not move to the next or previous item.

In COMBO would be interesting to know if the value of combo has changed by a msg in cb function.

setRootChangeCallback , i think not server:

m2_menu_entry m2_2lmenu_data[] = 
{
  { "Menu 1", NULL },
  { "Menu 2", NULL },
  { "Execute", &top_el_dummy },
  { NULL, NULL },
};

void dummy_fn(m2_el_fnarg_p fnarg)
{
  arr = (TimeAlarmsClass *) malloc(sizeof(TimeAlarmsClass) * 10);
  for(int i = 0; i < 10; i++)
	Serial.println(arr[i].getTriggeredAlarmId());
        digitalWrite(RL1,ON);
	delay (1000);
	digitalWrite(RL1,OFF);

	m2.setRoot(&m2_null_element);
}

M2_BUTTON(top_el_dummy,NULL,"CONFIRMAR",dummy_fn);

From a menu item. I want to execute a function
It is made with a button but I do not want to use the button.
I need an item that does not show anything and know that the menu item was who called

Thanks very much by the interest

Best Regards
