How To Remove Search Box From Header Arras Theme. I have reviewed all the past post and it is confusing to try to figure out which version of wrod press the answer refers and some talk about the header others talk about the .css files. It is hard for me to belive this requires editing code. The Sidebar Search is a Widget and is very eay to add or remove. Also when I look at the code via the Editror from the Admin panel, I can see the code but do not know how to chnage.
