In digitalether (in my opinion) there is a much better menu than the drop down system in Colormatic
Is there a particular reason the drop down from digitalether isn't used anymore, or do people just prefer the newer drop downs?
DigitalEther uses Transmenu whereas Colormatics utilises Suckerfish. Transmenu, with being pure javascript, can cause lots of problems and conflicts within a site. It is best not to use it to allow for a more diverse compatibility for all members.
I personally love the Transmenu but Suckerfish suits me fine. However, there is a new 'off-spring' of the 2, superfish which may be a much better option in future templates. It still has the sliding effects of Transmenu but lesser conflicts, GollumX posted a thread about it.
