I have searched and tried many menu extensions but not found any that works right for me.
I need one that can handle long lists of categories and up to 5 levels in drop-down.
Scroll in drop-down menu or multi-column drop-down would work fine.
It also need to hide not used and activated categories.
Is there anyone that knows about a menu extension that can handle that or maybe want to help me make one?
Like this http://tsdtuning.se/ ( this is our old site in Woocommerce and we are building a new in Magento )
when we are trying to do this in Magento it disappear behind the bottom of the browser frame because it get to long.
