menuID="menu_id"

This attribute is required for menu buttons and combo buttons, unless you specify the getMenuID() function in an associated command file. Adobe Dreamweaver ignores the menuID attribute for other types of items. This attribute specifies the ID of the menu bar that contains the context menu to pop up when the user clicks the button, menu button, or combo button. The ID comes from the ID attribute of a menubar tag in the menus.xml file.

Example

menuID="DWCodeNavPopup"
