I could go ahead and order a pre-made navigation menu, but then I though why not come here and pay that money to someone here, who can have customized made menu for me. In the past I hired someone here to do some job for me and I was satisfied with his job.
This menu should be a combination of JS, CSS and runs on jQuery.
The important part is, it should be sticky on scroll. Means when scrolled down, it should stick on top of the page.
It also should have multilevel dropdown; means, it should support sub and sub-sub levels.
Also, a search bar somewhere in the menu. possibly on the right-side.
It also should be responsive for smaller screens like smaller than 750px.
In smaller screen it should disappear and when clicked on toggle, it should slide in screen from left, with dark screen in the back, that with touch it should slide out of screen.
