Hello,
You can easily customize your main menu by following these steps:
1. Go to Appearance > Menus.
2. Select the menu that is set as your main Menu.
3. From there, you can:
Rename the “Shop” menu item to any name you prefer (just click the dropdown on the menu item and edit the Navigation Label).
Remove any unwanted items by clicking the dropdown on each one and selecting Remove.
Rearrange items by dragging and dropping.
Best Regards,
