Toggled WP Search Function in Spirit?

Hello,

I would like to incorporate a toggle effect for the built-in WP search function. I attempted the method at the following link, with no luck: http://www.wpbeginner.com/wp-themes/how-to-add-a-search-toggle-effect-in-wordpress/

Is that method compatible with Spirit?

Alternatively, implementing search functionality similar to the one on my other WPMU Dev-connected site (se***********th.com) would also be okay.

Support access granted, if you need it. Please perform any testing on the stage_addsearch1 site.

Thank you so much!
