Divi Mobile Anchor Points
If you have a scrolling website where all the links on the Mobile Menu are on the same page, by default when clicking a menu item it will not automatically close.
To make the menu auto-close when you click on a menu item - follow these steps.
1) Go to Appearance > Menus
2) Enable CSS Classes
At the top right of your screen you will see "screen options" - click on this and then check the box for CSS classes
3) Add the class "anchorpoint" to your menu items
