Ok, I understand.
You speak about the menus.
You must change the manifest XML file.
Note 1 :
You must reinstall your component to see the changes, because this menu is created in database from this manifest during installation.
Note 2 :
Unfortunatly, the fork system does not works on this file.
So you must do the chenges in the generated manifest file.
Remember to keep your changes.
I usually put it in the fork folder as well as a backup copy.
Every time you make a change in this manifest file, override the copy backup in the fork directory.
Every time you reinstall a fresh install, do the opposite: Pick the manifest file in the fork folder (unchanged) and override the xml file.
