was able to do this after your answer. Thank you!
there is another question: on my lending there are 4 screens, two of which have a parallax effect, and two — haven`t. How can I connect the parallax effect to each screen on landing page? litle video
You have forgotten to attach video. Actually, you assign ID to a row or section, not to parallax effect. And a row or a section in their turn can have the parallax effect. Parallax is like a background – it is just configuration. If I misunderstood your issue give more details.
Yes, I understood your aim. Now I check your menu and when I click these menu items http://prntscr.com/j6286w I get to the block on your landing page accordingly.
Please clarify your difficulty. Now I see the menu configured properly.
