How to add submit button to search box?
 

Hello,
I'd like to ask how can I add a submit button for the search box on the top of the page?

This is how it looks currently:

And this is what I want to be (not exactly looking like this, I know how to style it, I just don't know how to add the button to be there):

Thanks very much in advance!

I would look for a search plugin.
