+-- # Description:
+--
+-- Very simple example of the MENU_GROUP.
+-- We added two planes and give them different menu entries.

+--
+-- # Guide:
+--
+-- 1.  Start the mission.
+-- 2.  Enter as Plane-1.
+-- 3.  Wait for "loaded successfully" message and then 5 seconds more.
+-- 4.  Open menu by pressing #
+-- 5.  Choose F11. Parent Menu
+-- 6.  Choose F10. Other...
+-- 7.  Select F2. Menu for Plane-1...
+-- 8.  Select F1. Accept CAS mission and see the message.
+-- 9.  Switch to Plane-2 and wait 5 seconds.
+-- 10. Open menu by pressing #
+-- 11. Choose F11. Parent Menu
+-- 12. Choose F10. Other...
+-- 13. Select F2. Menu for Plane-2...

+
+
+-- Example function
+local function PrintTheTextToBlue( text )
+  MESSAGE:New( text, 25, "INFO" ):ToBlue()
+end
+
+-- Start a scheduler after a delay of 5 seconds and repeat it's execution very 5 seconds
+SCHEDULER:New( nil,
+  function()
+    -- Find both groups and save them in an object
+    local PlaneGroup1 = GROUP:FindByName( "Plane-1" )
+    local PlaneGroup2 = GROUP:FindByName( "Plane-2" )
+
+    -- Add menu for the first group
+    if PlaneGroup1 and PlaneGroup1:IsAlive() then
+      local MenuGroup1 = MENU_GROUP:New( PlaneGroup1, "Menu for Plane-1" )
+      MENU_GROUP_COMMAND:New( PlaneGroup1, "Accept CAS mission", MenuGroup1, PrintTheTextToBlue, "Plane-1 accepts the CAS mission" )
+      MESSAGE:New( "Menu added to Group1.", 1, "INFO" ):ToLog()
+    else
+      MESSAGE:New( "Group1 is not available.", 1, "INFO" ):ToLog()
+    end
+
+    -- Add menu for the second group
+    if PlaneGroup2 and PlaneGroup2:IsAlive() then
+      local MenuGroup2 = MENU_GROUP:New( PlaneGroup2, "Menu for Plane-2" )
+      MENU_GROUP_COMMAND:New( PlaneGroup2, "Accept BAI mission", MenuGroup2, PrintTheTextToBlue, "Plane-2 accepts the BAI mission" )
