using jquery ui 1.8 trying autocomplete
Everything works apart from that the ui-menu isn\'t positioned under my input element, but rather in the top left corner.
I had a similar issue, and after searching I found out I was missing a JS to fix this. In case someone stops by ensure to have a the "jquery.ui.position.js" script called as well.
See http://jqueryui.com/demos/autocomplete/ under dependencies: UI Core UI Widget UI Position
I simply changed my jquery-ui.min.js to the latest version and it fixed the positioning.
from 1.8.16 to 1.8.23 and it worked!
