It’s very easy to change the style and to configure the menu behavior. The navigation through the menu is very easy, fast and precise even for very deep menus.
There is no auto column width.
Its use is very limited without the plugin which is not free. Especially if you want to define different column widths for each menu level and keeping the small arrow in place.
The configuration for different column widths it’s not easy. It seems there is a problem in the menu core, but I manage to understand the problem and contour it playing with the settings. Young players can easily run crazy with this.
I didn’t buy the plugin but I was able to make my own plugin in a couple of hours. But if you don’t want to spend time programming, buy the plugin!
I start playing with Joomla one week ago and this was my first experience with web-programming, PHP and MySQL.
