Fix the menu for the mobile version.

Hello.

We need an experienced maker.

Interested in refining the drop-down menu for mob. Version.

In particular, the refinement concerns Andoird and iOS, because now the menu almost works correctly for iOS devices (iphone, ipad) and not quite correct for Android, namely:

for Android: When you open one substitution and scroll the page down in the menu, sometimes the opening of another spoof does not work, the other spoof can only be opened by closing the previous one. But at the same time, I open the substitution, if you open them from the bottom up.for iOS: sometimes, when you are on the page of goods, and scroll through the page, then open the menu, and sometimes does not open a spoof (for Android such a problem is not). Also, when you open one item, the menu does not scroll through the rest of the menu, and you can not see other items.

Scroll itself in the menu is not as smooth as when scrolling on the product page, for example - its for both operas. Systems.

In general, you need to improve the work of the menu when scrolling through the page, opening/closing the spoof, etc.

All the questions, please.
