Thanks for your reply. However, I did not fully understand what you meant. Sorry, I am new to WP.
1) Are you suggesting that I use use my Categories as Menu items and not create separate pages? I am actually currently using Top Menu as theme location for my Main Menu. However, I have pages in my Menu instead of Categories and new pages do not by default have the same layout as Categories.
2) I actually wanted to have separate pages for each main category. Is there a way of having the same layout for pages as well?
3) In case I do use Categories as Menu; in terms of SEO, is there any downside/disadvantage of not having any pages in your site and instead have all navigation/menus based on just Categories?
I’d really appreciate if you can help.
