Need to develop header in react js bootstrap

I want you to develop the responsive header with the animated search bar. As shown in the mockup. On the hover dropdown menu, it should show the normal menu for one and megamenu for others respectively. Active menu color and up-down arrow transition are required. The remaining requirement is clearly shown in the mockup. I will give you the mobile view design after completing the desktop version.

Budget is fixed. If it not under your budget please do not bid.
