This code enables you to add a expanding search form in the Navigation menu of any WordPress theme. The code is tested in the Genesis Sample child theme however it will also work in any other WordPress theme as it uses WordPress hook and not a theme specific hook.
Update : If using the latest Genesis Sample theme, use this new tutorial instead.
Here’s the expanding search box in action:
The code uses PHP to add the search form to the nav menu and CSS for the effects, No jQuery used.
