Sticky Menu is not working.

Why do you need a Secondary and Primary Nav on desktop ?
Is it ONLY because you want to style them differently eg. second items to the left, and primary items to the right?

If so then you can combine them into one menu.
Give each secondary item a CSS class of secondary-item

We can then use some CSS to style and position the secondary-items differently.

Is that an option ? Let me know

I guess it wouldn't work.

Because the secondary menu has to change according to the status of login.

I think it is complicated to make sticky menu for my case..

What changes in the menu depending on the login ?
