i would create this Navigation. i have try some things with css and js. but it works not on every browser and i think the code is dirty.
the driangle of the navigation-hover is center of the length. the transparent driangle is lay under the blue driangle and the body of the Subnavigation (or undernavigation) is flexible in width.
have you some ideas to create this navigation clean? and possibly without JS?
i hope you can help me. i have spend so much hours and it does nt correct work.
yours, yellow
