As you can see in the ss that the navigation menu on the website is vertical. However, it is supposed to be horizontal at the top as displayed in the theme “Brooklyn”.
Please help me set this to a horizontal menu rather than the vertical one.
Sorry you are facing this issue, it would be my pleasure to help you.
