Links in the top menu bar

My intention is to create a site on one page, but I don’t understand how can I create links in the top menu bar to go further down the page and to go to the differents widgets/sections of this page without scrolling???
Thanks

It’s easy. You just need to add the ID of the section you want to target. You can do this by going to Appearance > Menus > and add Custom Links.

Now, your custom links will be in this form #pg-220-3(just an example).
This is how they are built:
#pg-PAGE ID-ROW POSITION
The page ID can be found if you edit your page and check the URL bar in your browser and the row position starts from 0 to the number of rows you have.

thank you very much
