Hi

I sent a private message with the data access.
Have you tried to scroll to the very bottom?

Hi Yuriy Kostenko,
I'm sorry.
You install our product the bottom is unreasonable . Sticker menu when you want out, you have to pull down 500px browser it appears.
Thanks!

"down 500px" - this is unacceptable. Where can I change this?
Makes sense create the appropriate setting.

Hi Yuriy Kostenko,
If you want to change it
Please go to script.js file(modules\mod_jux_megamenucss3\assets\js)
line 22 and 23
Thanks!

The set parameter coming from the upper edge of the content area. On my site is works poorly. The website has a very large header area. We need to start counting from the top of the page.

Hi
If more content. you must adjust its value. But your site can not roll, I think it does not make sense sticky.
Thanks!
