How to link Front Page sections on the menu
As you can see in the demo site, the main menu items links to the different Fron Page sections.
You can do this by adding custom links in your menu.
Go to your Admin Panel > Appearance > Menus create a new menu and select "Front Page Menu" as Theme Location:
The Front Page Menu is only for your Front Page, for all other pages you will see the Primary Menu.
Then you can start adding your menu items using the Custom Links option.
For example to link to the Services Section use the ID for that section, which is: "#services-section"
Each Front Page section has an ID for this, here is the list:
#services-section #quote-section #video-section #testimonials-section #image-section #team-section #phone-section #tagline-section #clients-section #map-section #pricing-section #portfolio-section #blog-section
Add as many items you like and then click on Save Menu
