Did you try below:
1. Give LI of 'Asia' an ID, <li id="asia">Asia <ul>....
2. Add the script in page "Asia":
<script> amenu.close(false); amenu.open("asia", true); </script>
You are just not going to take this question asked by so many people on board and answer it... Are you ? It is a perfectly logical thing that people are trying to achieve. I have the same problem.
