Hi
I want to show a keyword suggest bar front my visitor, which mean when a visitor type certain keyword on the bar he will get a result for keyword suggest

But I want to do this with WordPress plugin or theme

With some little coding skills, you can parse any Keyword Research API and put that on your little keyword form

Not free though.

Maybe the API from Google KP could also help

Although it may probably have some "free daily limits", which might not be very high (maybe 100 keyword checks per day, not 100% sure)
