Delphi Dynamique Des Éléments De Menu

J'ai un menu déroulant qui a quelques éléments qu'il contient.

Option 1 
- Sub1 
- Sub2 
Option 2 
- Sub1 
- Sub2 
Option 3 
- Sub1 
- Sub2 

Je veux être en mesure d'ajouter un sous-Sous-menu de l'Option 3, sub2 de sorte qu'il pourrait ressembler:

Option 1 
- Sub1 
- Sub2 
Option 2 
- Sub1 
- Sub2 
Option 3 
- Sub1 
- Sub2 
- Dynamique Item1 
- Dynamique Item2 
- Dynamique Item3 

J'ai essayé de travailler avec le code suivant à comprendre, je peux le faire "SI" l'option de menu n'est pas déjà là (Option 3), mais je ne peux pas le faire si l'Option 3 est déjà là (Il crée une copie de l'option de menu)

Comment puis-je faire?

Merci
