Hi,
1. Theme Options > Header builder > Search > Search By Category > Off
2. Theme Options > header builder > All department menu > https://prnt.sc/vhz5v8
Menus can be changed via Appearance > Menus. Do not forget to enable Elementor for static blocks – https://prnt.sc/vhz6ni , to be able to edit static blocks that are used in the menu.
3. Theme Options > Header builder > Top header > Content Zoom (%)
4. I suppose you need to use other elements in the footer to achieve the mentioned result, for example – https://prnt.sc/vhz9pq
