Go to Page Attributes, in the right column of the page, and choose
from the drop-down menu the page template "One Page Menu".
Create new custom menu from Dashboard > Appearance > Menus > Create a new menu
Please use "Links" option to add each menu item.
Create menu item for each column section of your page. Title of the column can be used as the Link Text of the menu item.
Fill in the URL field the full page's URL, next # and the column's ID, that you have copied in Step 1.
Please note that in order for this to work properly (as in, avoiding false positives), you must use the full absolute url including the page's title.
