Hello,
Thank you very much for choosing our theme and for contacting us.
Please navigate to Woodmart > Header builder http://prntscr.com/iyd2pe
Choose the proper header type (your current) http://prntscr.com/iyd333
Remove the menu element http://prntscr.com/iyd3h3 or set another menu instead.
All the screens are made from my site, your site will have other elements however the way is the same.
In order to change the main color, navigate to the Theme Settings > Styles and Colors and configure the colors as per your needs.
Best Regards
