Secondary sidebar has unwanted search, categories and archives.

I can't remove the search, categories and archives from the secondary widget area. I still want to use some widgets though, to be determined by the client. So this code won't work:
.sidebar {
display: none;
}

Here is the site. http://projetter.com/camera-inspection/

 

Hello,

Search, categories and archives are the default widgets, if you don't choose any widgets then it will display by default.
If you want to remove it, you have to add some widgets in sidebar.
All by default widgets will remove.
