You may add anchors to the menu on our theme to link it with the certain sections on your site. To do so, go to Appearance > Menus. Click to tab ‘Custom links’ and then type the anchor in URL file (for example ‘#example’). It may be any name useful for you. Than edit your page and find section that you like and add there just ‘example’ (without #). Now, when you click on the menu item, it’ll direct you to the anchored section.
