shortcode in widget?

I have to have 3 columns in the footer and it must be the original footer above the copyright and the extra space below, so I’m using the footer widget with column-group and one-third but I see the shortcodes on the website pages. Does this work with widgets? If not, that’s ok. I’ll just need to figure out something else. It’s a great plugin!
