jQuery UI Autocomple IE 6 Select List z-Index Issues

If you are using jQuery UI's Autocomplete control, your IE6 users may experience some issues when the autocomplete suggestions overlay a HTML <select> list. The autocomplete suggestions show up behind the select list in Internet Explorer 6.

To fix this you need to simply include the bgiframe plugin in a script tag on your page. The jQuery UI autocomplete control will detect bgiframe and use it to fix itself for IE6.
