When using jquery autocomplete in a frameset, the list of suggestions is hidden behind the lower frame. When using a usual Html select field - values are shown on top of the lower frame (as should be).Html select - OK jquery autocomplete - hidden - not OK
Working with framesets is enforced in this project by the framwork... nothing we can do about that.
I'd suggest two things mate,
a) Increase the Height of your Frame, say may be atleast 200px
b) Set the following css in the same page as autocomplete:
Hope this helps !!
