Symfony
I see html examples on the internet and think i miss the examples in the real world. So i started a symfony project and incapsulated this nice template and styles. I set it up with an actual user frontend using the FOSUserBundle. And exaple menu builder you can actually use, using the KnpMenuBundle. You can find it on the github page.
Submenu
When i was setting up the symfony bundle i could create menus and found the third level was not styled. I did want to do that so i updated the styles. Now it does, nice.
