[RESOLVED] Add a child menu items in code to MenuStrip in C#?

I have a MenuStrip in Form, in there I had many Menu items:
-a
--b
--c
--d

I want to code to have:
-a
--b
--c
--d
---e
---f

How to do this? Thanks.

You would just add the new items to the appropriate item's DropDownItems collection.

Thanks. I have resolved!
