It wouldn’t be that hard to do it on hover. All you have to do is check the input, if the value isn’t empty, don’t slide back up.
You could also check for focus on the text input.
In fact, there is one that slides over behaving exactly that way on a site I’m deving right now (I am doing CMS implementation, the JS was written by an outside company).
