I am using FlatUI Pro and was failed to add autocomplete to tagsinput control.
I used code from https://github.com/xoxco/jQuery-Tags-Input. It doesn't work with FlatUI. Could you provide working sample?
tried few things without luck. Best I got is when typing: 'X results are available...bla-bla'. I understand it is to do with CSS
tagsinput in rewritten now, please check it out.
