Get rid of JavaScript beahaviour through custom code

Howdy! I’ve developed a site for a client that uses Colors & Swatches plugin.
http://kenallhandbags.com/collections/shoulder-bags/drap/
In the product page, I would like to get rid of color selection behaviour.
That is, when you select a color, you will notice the whole page moves down.
(Notice I am hiding some e-commerce elements since the client is not ready to deploy a full e-commerce solution).
I would just like to eliminate this movement while keeping the “Reset selection”option.
Hope somebody can help! Thanks indeed
