Hi @iach 👋
You have asked an excellent question. Correct me if I am wrong – but I think you would like to convert your site into a “one page” format, yes? So, if I click on an “About” link on the menu, the page scrolls down and displays the “About” section. Similarly if I click on “Contact” on the menu, the page scrolls down to that section… and so on. Did I get this right?
If that is the case, you might need to make some changes to your site to achieve this functionality. The best way to achieve this is by installing a “One page” WordPress theme, which directly converts your site into a one page format. Please check the following article which offers some references on how you can achieve this look: https://themeisle.com/blog/create-a-one-page-website-on-wordpress/
I hope this guides you in the right direction. Let us know if you have any further questions!
