I managed to get the tool you suggested installed, after a number of errors referencing the path was not recognized, and the publisher could not be verified. But when I attempt to use the extension, it was unresponsive when I went to Insert > Ajatix > Advanced CSS Drop Down Menu Light.
Perhaps it is not compatible with CC?
Any ideas of what may be going on? Or perhaps another extension?
And a question that hopefully Adobe staff can answer. DW CC has many great widgets under Jqueryui, why was a menu option left off?
