Adding objects to the Insert menu
To add or control the position of an object on the Insert menu (or any other menu), modify the menus.xml file. This file controls the entire menu structure for Adobe Dreamweaver. For more information about modifying the menus.xml file, see Menus and Menu Commands.
If you plan to distribute the extension to other Adobe Dreamweaver users, see Working with the Extension Manager to learn more about packaging extensions.
