I'm using jQuery-ui 1.11.4. I've set up a menu to run horizontally across the top of the screen (by floating top-level li's to the left). The submenu default position is "my top left at top right". I want it to be "my top right at bottom right", so it won't interfere with movement in the top-level menu. When I specify this (or any other value), the y-axis is always "center". I've tried using various pixel adjustments as well, with no change.
Sounds suspiciously like a value is being set to zero when it shouldn't be, so I smell a bug. Here's a jsFiddle and here's my code:
I've also tried using previous versions with the same result, as far back as 1.8.0 (although that one had other problems as well). Can anyone show me why this isn't a bug?
