This menu module offers almost all features of the mainmenu module plus many many more.... Like: - CSS- Menu with Sub-Menues - patTemplate support - split the menu up (e.g. sub-navigation on the side) - navigate through sections, categories, content items (you can even make it expand regular section/category link menu items) - plugin support (load menu items from a custom database table or create complex views) - use one of the available menu templates (mainly based on other great resources like the suckerfish CSS menu, an accessible dTree menu, mountain-top rounded corners...) or create/modify your own menu template (you may want to make this one then available to others). (please see the homepage for more details) Just an additional note as some may misunderstand some things about this module: - it main emphases is not to make it simpler than the built in mainmenu but add some more possibilities and sacrifices some simplicity for flexibility (separate sub modules could probably be created to overcome this)... - those are mainly focused on giving the web developer/designer the possibility to create standard based web sites (menu wise) - that is to be able to separate structure (HTML) from design (CSS) - for integration, design and other reasons this is not a component but just a module with it's limitation - (a required step may not be required for a later Joomla version) This may help your decision: - don't use this module if you don't need/want any of it's additional features - don't use it if you are not sure what HTML/CSS is and you actually don't care about web standards (accessibility etc.) - if you desperately want JavaScript/Flash effects other menu modules may suit you better (even though possible there is not a lot effort put into making such easier) - otherwise just check it out.. it depends on your knowledge, preferences and what you actually want to archive
