Today I released a new tagged version of my Selectmenu widget forked from the Filament Group. This update includes a bunch of small fixes & improvements and a couple of new features:

• get rid of some positiong and browser jumping issues (hopefully)

• a new, more cleaner type ahead version which now supports both prefix matching and first letter cycling ('typeAhead' option now became the default delay)
• supports empty options
• now uses  jQuery 1.6.2 and jQuery UI 1.8.16.

See the full list of closed issues or the commit history.

Make sure you check out the new, built from scratch version of Selectmenu which uses the jQuery UI 1.9.x widgets Button and Menu.
