In previous versions of ColdFusion you were able to add custom menu items to the ColdFusion administrator by creating a template named extensionscustom.cfm and placing this within the cfadministrator directory.

Peek within the cfadministrator directory under CFIDE within ColdFusion 8 and you should see a file named custommenu.xml. By adding entries into this file you can replicate the behaviour offered by extensionscustom.cfm.

The XML file has the following structure:

You can have as many submenu or menuitem elements as you wish. Once you have made your changes, head over to the ColdFusion administrator and you should see your custom menu items appended to the end of the main navigation menu.
