Mega menu, do or don't ?

Hi all,

I'm currently building a large website (the plans are around 200 articles) and was wondering what's up with the mega menu.

When I go for user experience you want (almost) every page 'clickable', but for Google I can understand they see the pages due to the mega menu as 'same content' so they won't rank ...

Can you guys give me some information, is it a do or don't ?

Hope you guys understand the question Otherwise feel free to ask

Ideally you want to have less than 30 links on the menu. Consider this links will be on all the pages of the website, so all will be passing value to the pages on the menu. Make sure you have your main category and landing pages (organic) on the menu. The way to go around if you need more pages on the navigation bar is to have a secondary navigation bar on each section of the website. I have worked with websites with 80 links on the menu - seo killer.

Thanks for the answer iv4lm4n!

When all will passing value to the pages on the menu, I don't consider it as a bad thing isn't it? So when links point to my homepage they send value to the innerpages who will rank? Or Am i missing something big here?
