Fix menu on mobile

[vlukash]

I believe the right way to fix this is just to hide text that doesn't fit into the mobile menu item width.

Also the common approach is to add ... at the end of the string (text-overflow: ellipsis). So it looks like this:

CSS changes:

overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
