Hi Mike, i followed your advice and tested it, and on a desktop, it works like a charme. However, on a smartphone, once the page scrolls to "#s5_top_row2_area1" in my case, the hamburger menu disappears
, and I can't get it back. In other words I remain with the hamburger menu open and I can't close it to get back to the main page. Does it happen to you as well ?
If you want to see it, try accessing http://www.elementotango.it/test
The menu with the scroll function activated is the "Chi Siamo" one, and then the menu item is the 3rd from the top: "Le Attivit?". If you click it, you scroll down to the "#s5_top_row2_area1" section. When you do all this on a smartphone (I used responsivator to test it) you'll get the issue.
Thanks Mike again!
