in the moment we are using a mega menu Jat 3 for a Joomla 2.5.
What we exactly need is a changeable Menu for example with Ajax. It can be mod or Plugin whatever is better to realize.
That is how it should function:
We got 1 menu showing on the site ( mainmenu) on the right there is a little box with 3 check boxes called "show menu 1, 2 or 3" , when you push button then it shows immediate the menu 2 or 3 without leaving the website or a new load of the website.
Get in touch with mike web4europa he can provide the instructions.
Thanks your Web4europa
