Hello,
The type of the header that you provided https://imgur.com/RfEWO11 is not standard, it’s the double menu http://prntscr.com/ov1562 Standard header type design is different.
To add menu there go to Appearance > Menus > create the menu and choose its location – right http://prntscr.com/ov15xa
To enable search go to Theme Options > Header > Search > choose the search position header http://prntscr.com/ov16o3
